Image Processing (imgproc module) {#tutorial_table_of_content_imgproc}
=================================

@tableofcontents

The imgproc module in OpenCV is a collection of per-pixel image operations (color conversions, filters) drawing (contours, objects, text), and
geometry transformations (warping, resize) useful for computer vision.
Here's an overview of the content in the imgproc module, categorized for easier navigation:

##### Basic
These tutorials cover fundamental image processing tasks, such as drawing on images, applying filters, and morphological operations.
