A command-line toolkit for learning and implementing image and video processing algorithms — from fundamentals to advanced techniques.
TermiView is an open-source command-line toolkit that transforms your terminal into a complete lab for image and video processing.
It helps you learn how digital images and videos are processed at the algorithmic level — by letting you build, visualize, and experiment with actual implementations in C.
Starting with colorized ASCII rendering, TermiView expands into a suite that demonstrates:
- Core image processing fundamentals
- Frequency-domain transforms (DFT, DCT, DWT)
- Compression algorithms (Huffman, JPEG, wavelet)
- Motion estimation and video coding concepts
Every module is implemented transparently, making it ideal for study, experimentation, and learning.
- Converts images into ASCII art with configurable color modes (grayscale to truecolor).
- Applies convolution-based filters such as Gaussian blur, sharpen, and edge detection.
- Demonstrates foundational topics like sampling, quantization, and transforms.
- Provides implementations of compression algorithms and motion analysis for video.
In short, TermiView bridges theory and code, offering a hands-on way to understand how visual data is processed at every stage.
- ASCII Renderer: Brightness-based mapping with color output (16, 256, truecolor).
- Image Filtering: Kernel-based convolution with multiple filters.
- Transforms: DFT, DCT, and DWT for frequency-domain analysis.
- Compression: Implementations of Huffman, LZW, and JPEG.
- Video Basics: Frame extraction, temporal filtering, and motion modeling.
- Modern command-line interface using
getopt. - Comprehensive error handling and memory safety.
- Modular Makefile with
install,uninstall, andtesttargets.
