As expected performance decreases with accentuated perspective and decrease in resolution. To improve performance and robustness, we propose a scheme to fuse color and gradient local descriptors. This approach is motivated by the discriminative power of color in man-made object recognition. The problem of color feature extraction is addressed as well as the considerations on the fusion process and steps to train such fusion. We used SOIL-47A database for experiments and shown a 7\\% to 10\\% relative improvement when compared with state-of-the-art gradient based descriptors.}, pdf = {https://publications.idiap.ch/attachments/reports/2003/rr03-71.pdf}, postscript = {ftp://ftp.idiap.ch/pub/reports/2003/rr03-71.ps.gz}, ipdmembership={vision}, }
