   Developer open-sources moray-ghost local GUI agent engine

   The developer of moray-ghost says it is an open-source local GUI agent execution engine with local vision, multithreading, Windows input handling, MCP support, and safety controls. It reportedly uses OCR and OpenCV to create a JSON directory of interface controls, allowing a model to select a control ID while the engine maps it to screen coordinates; the developer also demonstrated it drawing in Windows Paint with a physical mouse. Performance, precision, and production-readiness claims have not been independently verified.

   OCR Preprocessing Benchmark: Order and Strength Matter

   A first-hand benchmark tested 108 Tesseract preprocessing combinations on one English page and 60 macOS Vision combinations on one Chinese page. Deskewing and denoising helped Tesseract, but order and strength mattered: denoising before deskewing achieved 98.6–99.1 accuracy on tested salt-and-pepper cases, while a 9×9 median filter reduced English accuracy to 91.0. Otsu thresholding alone offered little improvement, and adaptive thresholding produced blank output under Gaussian noise in the tested configuration.

   Weekend YOLOv8-LPRNet Plate Recognizer Tops CCPD but Fails on Real Photos

   A developer built a runnable license-plate recognition pipeline in two days using YOLOv8n for detection, LPRNet with CTC decoding for text recognition, and HSV heuristics for plate color. The author reported 99% performance on CCPD, but real mobile-phone images exposed failures involving out-of-province plates, angled or distant shots, double-layer plates, screenshots, scans, and poor lighting. The article provides runnable code and recommends broader data, stronger augmentation, grouped evaluation, and a learned color classifier for production use.
