Progress in understanding the brain mechanisms underlying vision requires the construction of computational models that not only emulate the brain's anatomy and physiology, but ultimately match its performance on visual tasks. In recent years, “natural” images have become popular in the study of vision and have been used to show apparently impressive progress in building such models. Here, we challenge the use of uncontrolled “natural” images in guiding that progress. In particular, we show that a simple V1-like model—a neuroscientist's “null” model, which should perform poorly at real-world visual object recognition tasks—outperforms state-of-the-art object recognition systems (biologically inspired and otherwise) on a standard, ostensibly natural image recognition test. As a counterpoint, we designed a “simpler” recognition test to better span the real-world variation in object pose, position, and scale, and we show that this test correctly exposes the inadequacy of the V1-like model. Taken together, these results demonstrate that tests based on uncontrolled natural images can be seriously misleading, potentially guiding progress in the wrong direction. Instead, we reexamine what it means for images to be natural and argue for a renewed focus on the core problem of object recognition—real-world image variation.

Brinkworth and O'Carroll have come up with a new optical flow model, described in their paper, Robust Models for Optic Flow Coding in Natural Scenes Inspired by Insect Biology (PDF format). Their new system is based on the actual neural processing pathways of the fly which could prove to be a very robust velocity estimator and accurate sensor for self-motion in robots.

Dubai was meant to be a Middle-Eastern Shangri-La, a glittering monument to Arab enterprise and western capitalism. But as hard times arrive in the city state that rose from the desert sands, an uglier story is emerging.

iList is an Intelligent Tutoring System that can help you learn linked lists. It allows you to work on linked lists problems within an interactive, user friendly environment. However, iList is more than just a graphical environment: iList carefully monitors your progress and gives you helpful feedback while you are working towards a solution. The system does so by using sophisticated artificial intelligence technology. If you want to learn more about the science behind iList, you will find plenty of information in the papers referenced in the documentation section.

This project provides a easy to use Java binding for the OpenCL API and is released under the BSD license. GlueGen is used to generate a low level binding directly from the official Khronos C header files. A hand written high level binding on top of generated code provides a convenient interface and reduces verbosity to a minimum.

The generation of 3D models is very useful for many computer vision applications. This paper introduces ProFORMA, a system designed to enable on-line reconstruction of textured 3D objects rotated by a user's hand. Partial models are created very rapidly and displayed to the user to aid view planning, as well as used by the system to robustly track the object pose. The system works by calculating the Delaunay tetrahedralisation of a point cloud obtained from on-line structure from motion estimation which is then carved using a recursive and probabilistic algorithm to rapidly obtain the surface mesh.

tmux is a terminal multiplexer: it enables a number of terminals (or windows), each running a separate program, to be created, accessed, and controlled from a single screen. tmux may be detached from a screen and continue running in the background, then later reattached.

tmux uses a client-server model. The server holds multiple sessions and each window is a independent entity which may be freely linked to multiple sessions, moved between sessions and otherwise manipulated. Each session may be attached to (display and accept keyboard input from) multiple clients.

If you’re not yet aware of it, Google AppEngine is one of the foremost Cloud Computing offerings currently available. It is also arguably one of the purest options available, since it truly removes the need for the application administrator to consider physical resources (apart from paying for them that is!). The Google AppEngine cloud will automatically scale up the resources as and when required.

Procrastinators often follow exactly the wrong tack. They try to minimize their commitments, assuming that if they have only a few things to do, they will quit procrastinating and get them done. But this goes contrary to the basic nature of the procrastinator and destroys his most important source of motivation. The few tasks on his list will be by definition the most important, and the only way to avoid doing them will be to do nothing. This is a way to become a couch potato, not an effective human being.
