1. A method of identifying an object of interest in digital images, the method comprising: a. obtaining first samples of an intensity distribution of one or more objects of interest in one or more of the digital images based upon one or more wavelength bands; b. obtaining second samples of an intensity distribution of confounder objects in one or more of the digital images, at a predetermined frequency; c. transforming the first and second samples into an appropriate first space; d. performing dimension reduction on the transformed first and second samples, whereby the dimension reduction of the transformed first and second samples generates an object detector; e. transforming one or more of the digital images into the first space; f. performing dimension reduction on the transformed digital images, whereby the dimension reduction of the transformed digital images generates one or more reduced images; g. classifying one or more pixels of the one or more reduced images based on a comparison with the object detector; and h. identifying one or more objects of interest in the reduced digital images from the classified pixels.
