Abstract:
1. An embedded system using an image coding method, the embedded system comprising a processing unit, and the image coding method comprising the steps of: constructing a plurality of edge models with a Forward Discrete Cosine Transform (FDCT) algorithm, wherein the edge models each match at least one dominating coefficient; creating a plurality of adjustment equations each having at least one adjustment factor, wherein the adjustment equations correspond in quantity to the edge models to allow each of the adjustment equations to match one of the edge models; capturing an image comprising a plurality of pixels, by the processing unit; selecting the pixels of the image to define a plurality of image blocks, by the processing unit; detecting by block-edge detection (BED) a pattern collectively exhibited by the pixels in each of the image blocks, by the processing unit, and then comparing the detected pattern with patterns of the edge models, by the processing unit; changing the pattern of each of the image blocks to a pattern of one of the edge models, by the processing unit, and adjusting the at least one dominating coefficient of one of the edge models by the at least one adjustment factor of one of the adjustment equations after determining that the pattern of the image block approximates to the pattern of one of the edge models and matches one of the adjustment equations, by the processing unit; and performing a coding process on the edge models each having at least one dominating coefficient by LLEC to generate a compressed image corresponding to the edge models, by the processing unit.
