Image library

Image library for an interview I had with Apple. It is written in C++ and implements all the methods and algorithms without using libraries. The only exception is OpenCV, which is used for loading the input images and showing the outputs.

Functions

• Creation and destroy of an image

• Read an image from disk using OpenCV and convert OpenCV's image data to your format.

• Shallow and deep clone of an image

• Access to image elements and different properties of the image (grayscale or RGB, height, width)

• Convert a RGB image to a grayscale image

• Compute a histogram of an image

• Resize an image

• Perform correlation and convolution of an image with a kernel

• Perform edge detection on an image.

Dependencies

• OpenCV 4.3.0
• CMake 3.17

Compilation in Linux

$ mkdir build && cd build
(./build) $ cmake ..
(./build) $ cmake --build .

Instructions to run tests

(./build) $ ./Tests
