TECHNOLOGIES FOR DETERMINING LOCAL DIFFERENTIATING COLOR FOR IMAGE FEATURE DETECTORS

Technologies for multi-channel feature detection include a computing device to determine a filter response of each image channel of a multi-channel image for one or more image filters. The computing device determines a local differentiating color vector based on the filter responses, applies the filter responses to the local differentiating color vector to generate an adapted response, and determines a total response of the multi-channel image based on the adapted response.
