Abstract
An image comprising a set of pixels is obtained and a dominant hue is determined. A color value of individual pixels in a subset of the set of pixels that fall within the hue range is modified to produce a first transformed image. A filter is applied to the first transformed image or an image derived from the first transformed image to reduce spatial high frequency noise and derive a low frequency image. A high frequency image is generated based on the first transformed image and the low frequency image. Whether the high frequency image depicts the object at a target image frequency is determined based on specified criteria for an object, and if the high frequency image corresponds to the target image frequency, the high frequency image is stored.
