Object Classification

Stereo Vision

The primary motivation for our work is helping blind people

Interested

Interested

In Machine Learning

Using stereo vision techniques and narration to develop an object recognition system that help blind to independently navigate the surrounding.

Developing object classification system that may be useful for a large scale of applications.

Surveillance systems

Medical systems

Improve segmentation accuracy using the depth information.

• Complex scene• Segmentation problems [supposed to be enhanced with

stereo vision]• Recognition reliability

– Prevent misclassifications

• Invariance with respect to– Scale– Illumination– Rotation

• Background clutter– Especially natural images don’t show only the object, but also

contain background information

• Partial occlusion [supposed to be enhanced by selecting discriminative features to describe objects]
