Desktop application for local Laplacian image filtering developed in C#
Processor: Intel® or AMD processor with 64-bit support (2 GHz or faster processor)
Operating system: Microsoft Windows 7 (Microsoft Windows 10 recommended)
RAM: 2 GB or more of RAM
Minimal resolution: 1280 x 800 px
The application is designed for post-processing of raster images by correcting the dynamic range of brightness, local and global contrast, detail, saturation and exposure. It supports three color spaces: YCbCr, HSL, HSB and grayscale mode. The application includes the function of creating HDR-images from a series of images of different exposures (exposure fusion based on Laplacian pyramid technique [3]).
