Digital Image Processing Research Basing on the Embedded Linux System

The usual embedded image processing platform occupies mass storage space, lacks configurability, and the feature of real-time is not hard. This paper provides a method of designing digital image processing platform based on Qt. The method can improve the capacity of acquisition, analysis and processing image data to realize real-time and rapidity of the image processing. The work of software is based on the hardware, which completes the video driver firstly, and then achieves a variety of image processing methods involving transform domain and spatial domain, such as orthogonal transform, smoothing, sharpening, edge detection, emboss algorithm and so on.
