Image Analysis TRIZ Cases
- Computer Vision Audio Control for Conferencing Echo Reduction
Camera-based room mapping adjusts conferencing speakers and microphones to cut echo and ambient noise while improving voice pickup.
- Affine Picture Prediction Using Merged Motion Information Units
Merged motion information units cut affine prediction complexity while preserving accurate irregular-motion coding in picture blocks.
- Display Image Error Detection Using Foreground-Background Dissimilarity
Pixel-based foreground-background dissimilarity detects post-processing display errors that CRC misses, protecting icon visibility and shape recognition.
- LDPC Zero Padding for Fixed-Length Broadcast Signaling Frames
Selective zero-filled LDPC groups align BCH-encoded signaling to fixed-length frames, improving broadcast transmission robustness and efficiency.
- OLED Compensation Data Compression for Lower Bandwidth Storage
By encoding deviations from preset base values, OLED compensation data can be stored and transmitted with less bandwidth while preserving accuracy.
- Rice Parameter Initialization for Adaptive Coefficient Level Coding
Previous coefficient statistics set a non-zero Rice parameter per coefficient group, improving video coding efficiency for large values.
- Signature Generator Spanning Elements for Robust Object Detection
Sparse multidimensional signatures and spanning-element mapping improve object detection across angle and scale changes with lower compute load.
- Block-Based PCA Signal Transformation for Lower Computation Cost
By splitting high-dimensional signals into blocks, this PCA approach cuts computation cost and data size while preserving full signal recovery.
- Graphical Indicator Reading with Partial Image Data Recovery
Recovers missing graphical micro-units from adjacent indicators so incomplete captures still yield accurate indicator data.
- Dither Error Diffusion for PWM Moire-Free Image Processing
Selective error diffusion corrects PWM light-output errors in dithered pixels, reducing moire and pseudo contours in electrophotographic images.
- Structured Light Codeword Correction for Complete Depth Maps
Invalid structured-light codewords are corrected using neighborhood-based candidate selection to fill depth-map gaps and improve scene accuracy.
- LDPC Zero Padding for Variable-Length Broadcast Signaling
Group-based zero padding matches BCH data to fixed LDPC blocks, improving broadcast signaling robustness with manageable encoding complexity.
