Patent Images

1. A method of compiling thermographic data, comprising the steps of:

  • A) using a thermographic camera to obtain a thermographic image data indicative of a monotonically changing, thermal characteristic of a specimen,B) using an image processor to sequence the thermographic image data or a surrogate of the thermographic image data into a plurality of time based, thermographic image data frames,C) categorizing, for each frame, a frequency distribution of frame pixels, wherein each pixel is encoded with a thermographic image data value or a surrogate of a thermographic image data value,D) compiling, from two or more frames, a collection of the frequency distributions categorized in step C).
