## Features

- Support various image formats: encoded and Fourcc images (`[prefix_]WIDTHxHEIGHT.ext`):

    - `.jpg`, `.png`, `.bmp`, `.jpeg`

    - `test_1280x720.NV21`, `test_1280x720.NV12`, `hello_7680x4320.nv21`, `yes_640x480.i420`

    - `lena_1280x720.rgb24`, `lena_1280x720.bgr24`, `lena_1280x720.gray`

- Automatically compare and display difference image, just like Beyond Compare

## Usage

Click "Load" buttons to load images. Once both two input images loaded, the diff image is computed and displayed.

- Change `Tolerance` slider to get different compare result.

- Change `Zoom` slider or use mouse wheel to scale images.

See [images](https://github.com/zchrissirhcz/KantuCompare/tree/main/images) directory for testing images.
