C implementation of the Sobel and Robert's Cross edge detection algorithms.

C/C++ 8-bit PGM (Portable Gray Map) Image Processing Library

Lightweight image viewer written in C and SDL2

Imagetools is a school project for manipulate PGM and BMP images

A Utility program that can compress PGM images using Run Length Encoding Algorithm or reconstruct them without loss.

This is small image processing project which can read&write pgm images in C language and applies sobel edge detection on them.

Command line tool for processing of PGM images written in C. Rotating PGM images via rotation matrix.

Easy converting pgm and ppm to (MASK+FG+BG)-djvu.

High-performance Canny edge detector with CPU and CUDA implementations. Loads PGM images, performs Gaussian smoothing, gradients, non-max suppression, and hysteresis. Benchmarks both paths, outputs edge maps, and reports speedup. Simple Makefile, sample images included.

Perform histogram equalization and apply Sobel operator on the equalized image using MPI and libpng

This C program does 3 operations with a PGM image selected by the user.

Command-line Netbpm image editor that performs a variety of operations on PPM and PGM images

This project provides a collection of subprograms to handle image processing tasks in C. The utility allows loading, selecting, cropping, rotating, equalizing, and saving images in PGM / PPM format. It includes a histogram feature for grayscale images and efficient memory management using matrix structures.

Single-header library for handling PGM images.

Basic Operations on Image Processing Using PGM File Format

An application for plotting relations with two variables. Relations need not necessarily be functions.

Parallel image blur

Mirror of Netpbm. Netpbm is a package of graphics programs and a programming library. Original: https://sourceforge.net/p/netpbm/. Docs: https://netpbm.sourceforge.net/doc/.

Simple command line tool that converts a PGM image file to a Famicom/NES CHR tileset file
