wavelet-based, edge-detection, segmentation.
There has been much recent interest in the use of wavelet-based image compression schemes. They offer various advantages, not least the elimination of the need to segment an image prior to using the Discrete Cosine Transform (DCT). It is shown in this paper, however, that image segmentation and separation can produce an equivalent performance to more conventional schemes and can offer certain advantages. A wavelet-based image compression scheme is presented in which an image is first partitioned into high and low frequency segments and different wavelets are then applied using the 2-D discrete wavelet transformation (DWT).
