Application of Matlab-based computed radiography images to limb bone edge detection
AIM: To investigate the application of computed radiography (CR) images processed by Matlab to edge-detection of limb bones. METHODS: The edge of limb bone was respectively detected by the Sobel operator, Roberts operator, Laplacian operator and Canny operator from Matlab toolbox and the effects were compared. RESULTS: After median filter processing, the images obtained by Canny operator was the best in bone edge continuity and line smoothness, while the bone edges obtained by Sobel operator were more perceptive. Direct gradation processing could not satisfy the actual need. CONCLUSION: Canny operator from Matlab toolbox is better than other processing methods in limb bone edge detection.
