Abstract:
1. A method for high-resolution (high-res) location of an object in an image using a single-chip color image sensor that is sensitive to N bands of electromagnetic energy, the sensor having a sensor geometry, comprising: providing a high-res color model of an object; acquiring a color image of an object with the color image sensor; finding an alignment location of the high-res color model in the color image so as to provide a single low-res location having a phase, including providing N low-res single-band locations, one low-res single-band location for each of the N bands, and combining the N low-res single-band locations into a single low-res location; using the phase of the single low-res location, and using the sensor geometry, so as to provide a true-phase high-res color model having correct phase; and finding a high-res location of the true-phase high-res color model in the acquired color image.
