In this paper we analyse the influence of gamma correction of digital colour cameras on computer vision algorithms. These nonlinear signals R', G', and B' yield a nonlinear shift in colour space models and can cause algorithms to fail. Experiments of colour segmentation and tracking confirm the claims. We suggest to use linear light signals R, G, and B for calculating most colour space models instead...
Stereo vision algorithms are usually designed to run on standard PCs or PC-based systems. Up to now and due to the limited resources (e.g. internal and external RAM size, CPU power, power consumption, etc.) no general embedded hardware exists, where different algorithms can be implemented and run properly. The presented test platform aims to close this gap and implement a convenient platform for the...
This paper introduces a new segmentation-based approach for disparity optimization in stereo vision. The main contribution is a significant enhancement of the matching quality at occlusions and textureless areas by segmenting either the left color image or the calculated texture image. The local cost calculation is done with a Census-based correlation method and is compared with standard sum of absolute...
