Research On Several Digital Image Processing Algorithms Based On Photoshop Plug-in System

In recent years, with the expansion of image applications, image processingtechnology has been developed rapidly. It has become an important and usefultechnology in the field of image understanding and computer vision. Image processingcan not only make the processed image be more suitable for human to observe but alsoprovide effective information for further application. Digital image processing is widelyapplied, and it has penetrated into many fields.Based on the specific application, a research which is based on the system ofPhotoshop plug-in on several digital image processing algorithms is made in this paper.First, the paper introduces the basic knowledge of image processing and softwarePhotoshop. Then, we choose to write Photoshop filters, and give the knowledge of themain function of the filter frame. Finally, the paper introduces three algorithms:Gaussian blur, USM sharpening and Canny edge detection algorithm with adaptivethreshold. The main content shows as follow:1．Gaussian blur algorithm is introduced. Give the analysis of the algorithm, andthe improved algorithm.2．Introduce USM sharpening algorithm. Introduce the design process of thealgorithm and the three key parameters.3．Describe the traditional Canny algorithm and its features, then point out itsshortage that it need to artificially set the high and low threshold, and introduce animproved Canny algorithm with adaptive threshold.
