Abstract
Methods and apparatus are provided for low resolution item identification using brightness compensated images. An image of an unknown item is captured in digital RGB image format and converted to HSV image format. Then the HSV formatted image is quantized which greatly reduces the resolution of the image. The quantized HSV image data of the unknown item is compared to a plurality of quantized HSV image data for known items. The comparison includes using a signal-to-noise ratio calculated using the quantized HSV image data for both the unknown and known items. A match is found when the calculated signal-to-noise ratio is above a predetermined threshold value.
