System and method for detecting cancerous tissue from a thermal image

摘要

What is disclosed is a system and method for the detection of cancerous tissue by analyzing blocks of pixels in a thermal image of a region of exposed skin tissue. In one embodiment, matrices are received which have been derived from vectors of temperature values associated with pixels in blocks of pixels which have been isolated from a plurality of thermal images of both cancerous and non-cancerous tissue. The vectors are rearranged to form matrices. A thermal image of a subject is received. Blocks of pixels which reside within a region of exposed skin tissue are identified and isolated. For each identified pixel block, an image vector comprising temperature values associated with these pixels is formed. The vector is provided to a classifier which uses the matrices to classify tissue associated with this block of pixels as being either cancerous or non-cancerous tissue.

1. A method for detecting cancerous tissue from a thermal image, the method comprising:
receiving, with a processor, matrices AH of size m×H and AN of size m×N comprising vectors of size m×1 derived from temperature values associated with pixels in blocks of size p×q, where m=pq, which have been isolated from a plurality of thermal images of cancerous and non-cancerous tissues, where H and N represent a number of cancerous and non-cancerous blocks of pixels, respectively, said vectors being rearranged to form said matrices; receiving a thermal image of a subject; identifying a block of pixels in a region of exposed skin tissue in said received thermal image; forming a vector y of size m×1 derived from temperature values associated with pixels in said identified block of pixels; and providing said vector to a classifier, said classifier using said matrices to classify tissue in said thermal image represented by said block of pixels as being one of: cancerous and a non-cancerous tissue.
