Implementing image pseudocolor processing through gray level transformation and frequency domain filtering methods with MATLAB programming implementation, including algorithm explanations and key function descriptions
This MATLAB-based implementation includes sample images and is ready to run (requires path modification). Designed for crack detection in bridge decks and road surfaces, the code features detailed function descriptions and algorithmic explanations. Key implementations include frequency estimation of regular stripe patterns in road backgrounds and frequency-domain filtering to effectively remove noise near estimated frequencies while preserving target cracks. The current version provides basic detection functionality with room for improvement, serving as a demonstrative prototype. Interested developers are welcome to enhance and adapt this codebase - please contact me for collaboration opportunities.
Implementation using Radon transform for projection data generation followed by filtered back projection reconstruction with frequency-domain filtering and time-domain convolution approaches
Implementation of Generalized Sidelobe Canceller (GSC) adaptive beamforming method with time-domain and frequency-domain filtering using LMS adaptive algorithm for speech enhancement. The package includes clean speech samples and noisy speech samples with different SNR ratios for experimental validation.
