This software package collects some of the most widely-used algorithms in Image Processing and Computer Vision.
- Image rotation & Linear interpolation zoom
- Image smoothing, sharpening & gradient
- Histogram modification (negative, contrast, equalization...)
- Image morphology (erosion, dilation, gradient, smoothing, outlining...)
- Image segmentation: Automatic thresholding (hysteresis, entropy, Otsu, Pun, Kapur, Yager, two peaks, iterative selection, minimum error, relaxation...) & Texture segmentation (energy, contrast, homogeneity, entropy...)
- Edge detection: Laplacian, cracks, Marr/Hildreth, Canny, Shen/Castan, phase congruency...
- Fourier transform: Low-pass, band-pass, and high-pass filters (ideal, Butterworth, and exponential). Homomorphic filters.
- Haar's, Daubechies', and Walsh's wavelets.
- Hough's transformr to detect lines
All algorithms have been coded in ANSI C, while the GUI has been developed using Borland C++Builder.
