Machine Vision and Applications: Special issue on Benchmark Evaluation of RGB-D based Visual Recognition Algorithms

Visual recognition is a critical component of machine intelligence. For a robot to behave autonomously, it must have the ability to recognize its surroundings (I am in the office; I am in the kitchen; On my right is a refrigerator). Natural human computer interaction requires the computer to have the ability to recognize human’s gestures, body languages, and intentions. Recently, the availability of cheap 3D sensors such as Microsoft Kinect has made it possible to easily capture depth maps in real time, and therefore use them for various visual recognition tasks including indoor place recognition, object recognition, and human gesture and action recognition. This in turn poses interesting technical questions such as:

1. What are the most discriminative visual features from 3D depth maps?
Even though one could treat depth maps as gray images, depth maps consist of strong 3D shape information. How to encode the 3D shape information is an important issue for any visual recognition tasks.

2. How to combine depth maps and RGB images? An RGB-D sensor such as Microsoft Kinect provides a depth channel as well as a color channel.
The depth map contains shape information while the color channel contains texture information. The two channels complement each other, and how to combine them in an effective way is an interesting problem.

3. What are the most suitable paradigms for recognition with RGB-D data?
With depth maps, foreground background separations are easier, and in general, better object segmentations can be obtained than with conventional RGB images. Therefore the conventional bag of feature approaches may not be the most effective approaches. New recognition paradigms that leverage depth information are worth exploring.

Scope

This special issue covers all aspects of RGB-D based visual recognition.
It emphasizes on the evaluation on two benchmark tasks: ImageCLEF Robotic Vision Challenge (http://www.imageclef.org/2012/robot) and CHALEARN Gesture Challenge (http://gesture.chalearn.org/). The special issue is also open to researchers that did not submit runs to either of the two challenges, provided they will test their methods on at least one of the two datasets. In addition to the two benchmark tasks, researchers are welcome to report experiments on other datasets to further validate their techniques.
Topics include but are not limited to:

new machine learning techniques that are successfully applied to either of the two benchmark tasks o novel visual representations that leverage the depth data o novel recognition paradigms o techniques that effectively combine RGB features and depth features o analysis of the results of the evaluation on either of the two benchmark tasks theoretical and/or practical insights into the problems for the semantic spatial modeling task, and/or for the robot kidnapping task in ImageCLEF Robotic Vision Challenge o theoretical and/or practical insights into the one-shot recognition problem in the CHALEARN Gesture Challenge o computational constraints of methods in realistic settings o new metrics for performance evaluations

NIPS workshop: BigVision 2012

Big Data Meets Computer Vision: First International Workshop on Large Scale Visual Recognition and Retrieval (BigVision 2012)

Held in conjunction with NIPS 2012. December 7 or December 8 (TBD), 2012. Lake Tahoe, Nevada, USA.

https://sites.google.com/site/bigvision2012/

=============
Overview
=============

The emergence of “big data” has brought about a paradigm shift throughout computer science. Computer vision is no exception. The explosion of images and videos on the Internet and the availability of large amounts of annotated data have created unprecedented opportunities and fundamental challenges on scaling up computer vision.

Over the past few years, machine learning on big data has become a thriving field with a plethora of theories and tools developed.
Meanwhile, large scale vision has also attracted increasing attention in the computer vision community. This workshop aims to bring closer researchers in large scale machine learning and large scale vision to foster cross-talk between the two fields. The goal is to encourage machine learning researchers to work on large scale vision problems, to inform computer vision researchers about new developments on large scale learning, and to identify unique challenges and opportunities.

This workshop will focus on two distinct yet closely related vision
problems: recognition and retrieval. Both are inherently large scale.
In particular, both must handle high dimensional features (hundreds of thousands to millions), a large variety of visual classes (tens of thousands to millions), and a large number of examples (millions to billions).

This workshop will consist of invited talks, panels, discussions, and paper submissions. The target audience of this workshop includes industry and academic researchers interested in machine learning, computer vision, multimedia, and related fields.

===============
Call for Papers
===============

We invite high quality submissions of extended abstracts on topics including, but not limited to

–State of the field: What really defines large scale vision? How does it differ from traditional vision research? What are its unique challenges for large scale learning?
–Indexing algorithms and data structures: How do we efficiently find similar features/images/classes from a large collection, a key operation in both recognition and retrieval?
–Semi-supervised/unsupervised learning: Large scale data comes with different levels of supervision, ranging from fully labeled and quality controlled to completely unlabeled. How do we make use of such data?
–Metric learning: Retrieval visually similar images/objects requires learning a similarity metric. How do we learn a good metric from a large amount of data?
–Visual models and feature representations: What is a good feature representation? How do we model and represent images/videos to handle tens of thousands of fine-grained visual classes?
–Exploiting semantic structures: How do we exploit the rich semantic relations between visual categories to handle a large number of classes?
–Transfer learning: How do we handle new visual classes
(objects/scenes/activities) after having learned a large number of them? How do we transfer knowledge using the semantic relations between classes?
–Optimization techniques: How do we perform learning with training data that do not fit into memory? How do we parallelize learning?
–Datasets issues: What is a good large scale dataset? How should we construct datasets? How do we avoid dataset bias?
–Systems and infrastructure: How do we design and develop libraries and tools to facilitate large scale vision research? What infrastructure do we need?
–Submissions must be in NIPS 2012 format, with a maximum number of 4 pages (excluding references).

The deadline of submission is 11:59pm PDT, September 16th, 2012.
Submissions do not have to be anonymous. Accepted papers will be presented as oral talks or posters during the workshop. For detailed submission instructions please visit https://sites.google.com/site/bigvision2012/

CALL FOR ABSTRACTS AND OPEN PROBLEMS: Multi-Trade-offs in Machine Learning

NIPS-2012 Workshop, Lake Tahoe, Nevada, US
https://sites.google.com/site/multitradeoffs2012/
December 7 or 8, 2012
———————————————-
We invite submission of abstracts and open problems to Multi-Trade-offs in Machine Learning NIPS-2012 workshop.

Abstract
One of the main practical goals of machine learning is to identify relevant trade-offs in different problems, formalize, and solve them. We have already achieved fairly good progress in addressing individual trade-offs, such as model order selection or exploration-exploitation. In this workshop we would like to focus on problems that involve more than one trade-off simultaneously. We are interested both in practical problems where “multi-trade-offs” arise and in theoretical approaches to their solution. Obviously, many problems in life cannot be reduced to a single trade-off and it is highly important to improve our ability to address multiple trade-offs simultaneously. Below we provide several examples of situations, where multiple trade-offs arise simultaneously. The goal of the examples is to provide a starting point for a discussion, but they are not limiting the scope and any other multi-trade-off problem is welcome to be discussed at the workshop.
Multi-trade-offs arise naturally in interaction between multiple learning systems or when a learning system faces multiple tasks simultaneously; especially when the systems or tasks share common resources, such as CPU time, memory, sensors, robot body, and so on. For a concrete example, imagine a robot cycling a bicycle and balancing a pole. Each task individually (cycling and pole balancing) can be modeled as a separate optimization problem, but their solutions has to be coordinated, since they share robot resources and robot body. More generally, each learning system or system component has its own internal trade-offs, which have to be balanced against the trade-offs of other systems, whereas shared resources introduce external trade-offs that enforce cooperation. The complexity of interaction can vary from independent systems sharing common resources to systems with various degrees of relation between their inputs and tasks. In multi-agent systems communication between the agents introduces an additional trade-off.
We are also interested in multi-trade-offs that arise within individual systems. For example, model order selection and computational complexity [1], or model order selection and exploration-exploitation [2]. For a specific example of this type of problems, imagine a system for real-time prediction of the location of a ball in table tennis. This system has to balance between at least three objectives that interact in a non-trivial manner: (1) complexity of the model of flight trajectory, (2) statistical reliability of the model, (3) computational requirements. Complex models can potentially provide better predictions, but can also lead to overfitting (trade-off between (1) and (2)) and are computationally more demanding. At the same time, there is also a trade-off between having fast crude predictions or slower, but more precise estimations (trade-off between (3) and (1)+(2)). Despite the complex nature of multi-trade-offs, there is still hope that they can be formulated as convex problems, at least in some situations [3].
