| Abstract: | This paper takes digital image processing device as an application background to combine image process technology and embedded system technology based on S3C2440 core processor system. Firstly embedded Linux system is built, USB interface camera is selected for image acquiring device according to demand of image real-time processing. After completing programming video device, image can be obtain and saved. Based on embedded Linux system, GUI interface is designed using Qt to develop digital image processing platform. The image can be processed by various digital image algorithms involving transform domain and spatial domain which include orthogonal transformation, smoothing, sharpening, edge detection,emboss and so on. |
