Abstract
An array (map) of intrinsic images of an image of interest is established by selecting the intensities of a focused and defocused/diffused images of the image of interest. After obtaining a first focused image, a series of defocused/diffused images are obtained at different exposure times, where intrinsic images are obtained from the first focused image and the series of defocused/diffused images in order to form an array of image sets of the intrinsic images in the form of a matrix. In addition, a second focused image can be obtained at a different exposure time than the first focused image, and a second series defocused/diffused images are obtained at different exposure times, where second intrinsic images are obtained from the second focused image and the second series of defocused/diffused images in order to form an array of image sets of the intrinsic images and the second intrinsic images in the form of a matrix. The array of image sets cover and shows the required granularity of intrinsic differences among the intrinsic images generated enhancing the intrinsic images resulting in more noticeable details of the intrinsic image and the image of interest not previously appreciated.
