WebbThe objective of this first project is to develop and implement some image processing functions based on the histogram of an Image. In a first part we will present briefly some theoretical aspects associated with histograms and the processing associated. Then we will present the different functions and processing we developed for this project. WebbAn image histogram is a gray-scale value distribution showing the frequency of occurrence of each gray-level value. For an image size of 1024 × 1024 × 8 bits, the abscissa ranges from 0 to 255; the total number of pixels is equal to 1024 × 1024. Modification of original histograms very often is used in image enhancement procedures.

The first step of calculation in many feature detectors in image pre-processing is to ensure normalized color and gamma values. As Dalal and Triggs point out, however, this step can be omitted in HOG descriptor computation, as the ensuing descriptor normalization essentially achieves the same result. Image pre-processing thus provides little impact on performance. Instead, the first step of calculation is the computation of the gradient values.
