Matching clothes is a challenging task for many blind people. In this paper, we present a proof of concept system to solve this problem. The system consists of 1) a camera connected to a computer to perform pattern and color matching process; 2) speech commands for system control and configuration; and 3) audio feedback to provide matching results for both color and patterns of clothes. This sy...

In this paper we present a new method for point matching in stereoscopic color images. Our approach consists rst in characterizing points of interest using di erential invariants. Then we de ne additional rst order invariants using color information, which make suÆcient the characterization till rst order. In addition, we make our description robust to important image transformations like rotat...

Metallic coatings change in appearance as the viewing and illumination direction change. Matching of such finishes requires a match of color as viewed under different lighting and viewing conditions, as well as texture, i.e. matching the spatial distribution of color. The system described in this paper provides a purely objective and automatic match measure for evaluating the goodness of a colo...
