Abstract

parallelizable processing mechanism and multi-core architecture characteristics of image processing algorithm are studied. On the basis, image processing algorithm parallel design paradigm based on multi-core computing environment with five design procedures of analysis, modeling, mapping, debugging and performance evaluation as well as test publishing is proposed. Image Fourier transform parallel algorithm design is adopted as an example to verify the validity of the parallel paradigm. Meanwhile, a virtual input method based on digital image processing, operated in embedded system is also proposed. Camera equipment attached to embedded equipment is utilized for collecting image in user key pressing process on virtual keyboard. Keys are identified through corner-point identification and image segmentation in order to position target keys clicked by user through collected image, thereby realizing information input process. Experimental results show that the paradigm can expand application space of image processing in the aspect of image processing parallel design, thereby providing reference treatment method for interaction design of embedded equipment.
