data_struct_in_c_example

This an example of how to use data structs in c language. In this example, a departmental store is shown. the example allows to users select products from a category. In addition, at the end of the program, it is shown a note with the products acquired by users and the total spend to the buy by a user.

Image-processing-Algorithm-Contrast-Limited-Adaptative-Histogram-Qualization-CLAHE

In this reprositorio the CLAHE technique (Contrast limited adaptive histogram equalization) is presented, in the area of image processing one of the most used functions is the enhancement contrast, this technique is used when an image has a deficient contrast. Moreover, CLAHE was originally developed for medical imaging and has been shown to be successful in low-contrast imaging.
