发明名称 Image processing apparatus supporting both discrete cosine transform and discrete wavelet transform
摘要 An image processing apparatus supporting both discrete wavelet transform and discrete cosine transform with reduced hardware resources. The image processing apparatus is composed of an input unit receiving a plurality of pixel data, a controlling unit selecting a desired transform from among discrete wavelet transform and discrete cosine transform, and providing a plurality of coefficients depending on the desired transform, and a processing unit which processes the pixel data using the plurality of coefficients to achieve the desired transform.
