Application Background - Detailed explanation of the Criminisi algorithm for easy understanding! Currently, mainstream image inpainting models include PDE-based models [1-2] and texture synthesis models [3]. PDE models involve heavy computation, long processing times, and limited texture restoration capability, making them suitable only for narrow-area repairs like scratches and stains. Texture synthesis models extract features from surrounding areas and synthesize matching textures, making them ideal for larger damaged regions. Real-world images contain complex structures and multiple textures. Reference [4] proposes...

This software specializes in time domain experimental modal analysis for structures, supporting single-input single-output (SISO), single-input multiple-output (SIMO), and multiple-input multiple-output (MIMO) program designs. Unlike traditional modal analysis software based on frequency domain methods requiring Fourier transforms of sampled signals, our implementation processes measured time-domain signals directly. This approach eliminates adverse effects from signal truncation such as spectral leakage, side lobes, and low resolution that impact identification accuracy. The algorithm implementation reduces computational time and enables real-time online parameter identification for structures under actual operating conditions, providing more efficient analysis capabilities compared to conventional Fourier-based methods.

The neural network adopts a 4-5-3 architecture with a learning rate of 0.28, momentum coefficient of 0.04, and initial weight values randomized between -0.5 and 0.5. This configuration uses a feedforward design where the input layer processes 4 features, the hidden layer contains 5 neurons with activation functions, and the output layer generates 3-class classifications.
