Performance Optimization of Close-Color Pair

Abstract- Close-Color Pair analysis allows for a reliable means to determine if a given image contains a secret message. Counting such pairs for an entire image is computationally intensive, therefore, rendering the technique impractical when attempting to process large numbers of sizeable images. This paper outlines a proposed optimization technique that reduces the running time, while maintaining a reasonable (and controllable) error.
