Title: CAMERA ARRANGEMENT AND IMAGE PROCESSING METHOD FOR QUANTIFYING TISSUE STRUCTURE AND DEGENERATION
Abstract:
Methods and arrangements for detecting osteoarthritis (OA) relate to image processing for enhancing, visualizing and quantifying the fibrillation structure of cartilage using endoscopes. A structure enhancement method comprises obtaining input data, conversion to intensity data, preprocess filtering, intensity fluctuation filtering and contrast enhancement. The degeneration is quantified by a degeneration index (DI) algorithm, applied to the structure enhanced image. Results are then compiled in an output frame presentation.
