Color constancy investigated via partial hue-matching.
Each hue is believed to be made up of the four component hues (yellow, blue, red, and green). A hue consisting of just one component hue is called unitary (or unique). A new technique--partial hue-matching--has been used to reveal the component and unitary hues for a sample of 32 Munsell papers, which were illuminated by neutral, yellow, blue, green, and red lights and assessed by four normal t...
متن کاملDictionary Selection Using Partial Matching
This work concerns the search for text compressors that compress better than existing dictionary coders, but run faster than statistical coders. We describe a new method for text compression using multiple dictionaries, one for each context of preceeding characters, where the contexts have varying lengths. The context to be used is determined using an escape mechanism similar to that of predict...
متن کاملBilateral Maps for Partial Matching
Feature-driven analysis forms the basis of many shape processing tasks, where detected feature points are characterized by local shape descriptors. Such descriptors have so far been defined to capture regions of interest centered at individual points. Using such regions to compare feature points can be problematic when performing partial shape matching, since the region of interest is typically...
متن کاملEnsemble Prediction by Partial Matching
Prediction by Partial Matching (PPM) is a lossless compression algorithm which consistently performs well on text compression benchmarks. This paper introduces a new PPM implementation called PPM-Ens which uses unbounded context lengths and ensemble voting to combine multiple contexts. The algorithm is evaluated on the Calgary corpus. The results indicate that combining multiple contexts leads ...
متن کاملRobust Matching by Partial Correlation
Stereo matching by correlation near occlusions is a very challenging problem. When a partial occlusion occurs, most of the standard methods fail to produce acceptable results. This is because the techniques used do not take into account the presence of the occluding region. We propose a robust technique which we call partial correlation. This technique makes use of the least median square metho...
