1. A method for inspecting animal carcasses, comprising the steps of: (a) providing a processing system that moves animal carcasses past an operating line scanning camera; (b) obtaining lines of data from a carcass moving past the operating line scanning camera, each line of data comprising a series of pixels; (c) locating Region of Interest (ROI) pixels within each line of data and determining which ROI pixels indicate pixels corresponding to a wholesome carcass and an unwholesome carcass with a decision output parameter for each of the ROI pixels, wherein the decision output parameter is calculated immediately after obtaining each line of data; (d) repeating steps (b)-(c) continuously until decision parameters have been calculated for each line of data with ROI pixels associated with the carcass.
