Abstract:
A method for converting digitized image pixel values from a first range to a second range, the method comprising the steps of:(a) determining a lower limit value of a relevant portion of the first range based upon non-log transformed pixel values; (b) generating an intensity histogram representative of pixel populations having specified intensities, and transforming the histogram to generate a log-transformed histogram; (c) identifying a threshold value for an upper limit of log-transformed values from the log-transformed histogram; (d) identifying a population of pixels having log-transformed values having a desired relationship to the threshold value; (e) determining an upper limit value of the relevant portion of the first range based upon the identified population; (f) converting the non-lop, transformed pixel values to converted values; and (g) transmitting information relating to an image associated with the pixel values or source thereof between a first location and a second location remote from the first location to provide remote services.
