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

Pure C image processing library - Learn DFT/FFT, convolution, edge detection from scratch. Zero dependencies, perfect for embedded systems.

Lightweight image viewer written in C and SDL3

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

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.

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

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

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.

Politechnika Wrocławska -- Kurs: Podstawy programowania Autor: Michał Nowak -- Zadanie: Napisanie prostego programu do przetwarzania obrazów w formacie PGM

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

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

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

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.

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.

pgm image and GTOPO30 elevation data utilities written from scratch in C for COMP1921 - Programming Project at the University of Leeds.
