Scoring and adjusting pixels based on neighborhood relationships for revealing data in images

摘要

A machine/computer implemented system, method, and computer program product for scored pixel intensity value adjustment of a digital image is disclosed. The system is configured to obtain a digital image from data storage and perform pixel-by-pixel comparisons to generate per pixel scores. The types of comparisons include discovering minima and maxima per pixel scores by comparing to neighboring non-adjacent pixel pairs, delta pair scores by comparing to neighboring pixels, and multiple vector score types by comparing to vectors made up of individual pixels. This new information is applied to adjust each pixel's value. The system is further configured to generate a collection of such scores for a plurality of pixels in a digital image and to generate a multi-dimensional scored pixel adjusted image. The scored pixel adjustment yields a new digital image, wherein the value of a given pixel is adjusted based on one or more of the score types.

1. A machine-implemented method, comprising:
receiving a digital image having a collection of pixels each with a corresponding original value; processing each pixel as a centroid pixel surrounded by neighboring pixels; performing, for each of a plurality of centroid pixels, at least two of:
determining at least one of a minima score and a maxima score,determining a delta pair and a delta pair difference, anddetermining a primary vector set and a vector score; generating an adjusted centroid pixel value for each of the plurality of centroid pixels to increase a difference between the original value of each given centroid pixel and the original value of at least one of its neighboring pixels based on the performed determinations for that given centroid pixel and an adjustment function; generating a combined adjusted digital image based on all of the adjusted centroid pixel values; and outputting the combined adjusted digital image, wherein the receiving, the processing, the performing, the generating, and the outputting are performed by one or more machines.
