🖥️ image-post-processing

HDR, Histogram, Sharpen, Gamma correction, Bloom, Blur, Contour detection

Problem what I'm trying to solve:

• Image Filtering
• Gray scale algorithms.
• Blur algorithms.
• Sharpen algorithms.
• Bloom
• Contour detection
• Gamma correction (RAW to sRGB)
• HDR(Dynamic Range Compression)
• Noise Reduction
• Histogram viewer, Interactive tools

Install:

image-post-processing has an automatic installer. Copy the line bellow to your console and execute it. It will automatically download the repo, create the necessary folders.

bash -c "$(curl -fsSL https://raw.github.com/jeekpark/image-post-processing/main/install.sh)"

Execute:

Run the command below.

cd ./image-post-processing

./imagepp <file.jpg>

Features:

Grayscale convert

Average method

Calculates the average of the Red, Green, and Blue (RGB) values of each pixel.
(red + green + blue) / 3

Weighted or luminosity method

Human eyes are more sensitive to green. So diffrent weights are appilied to the RGB values.
(0.299 * red) + (0.587 * green) + (0.114 * blue)

Desaturation method

This method takes the average of the maximum and minimum values among the RGB components of each pixel.
(max(red, green, blue) + min(red, green, blue)) / 2

Single color channel

This method simply uses one color channel (such as Red or Green) for the black and white conversion.

Comparison of Four Types

Luminosity method is the best.

🏎️ Blur

Box

Gaussian
