Reduction of artifacts in a DWT-based compression scheme by adjusting inverse quantized transform data according to noise values |
摘要 |
A method of processing an image by generating transform data in response to performing at least one discrete wavelet transform based upon original image data, generating adjusted data by combining noise with the transform data, and generating compressed data representing the image by quantizing based upon the adjusted data.
