ponomarenko_multi_image

Extension of Ponomarenko Noise Estimation method for a sequence of images.

Usage

Compile:

mkdir build && cd build
cmake ..
make -j

Run the noise estimation program for a directory containing .png image files:

./ponomarenko_multi <image-dir>

More options are displayed

Test

Run the extended version on multiple images:

./ponomarenko_multi ../test_images/seq0/

Run the original version on a single image:

./ponomarenko_single ../test_images/seq0/image-001.png

Since the test_images/seq0 contains only one image, the outputs from two programs should be the same.

Example:
