Image registration is a crucial step in most image processing tasks for which the final result is achieved from a combination of various resources. In general, the majority of registration methods consist of the following four steps: feature extraction, feature matching, transform modeling, and finally image resampling. As the accuracy of a registration process is highly dependent to the fe...

body image is an internal representation of the external appearance which includes physical and perceptual aspects and attitudes toward them. body image anxiety can cause weight problems. in addition, perfectionism, the trend or effort to be perfect and flawless can cause extreme thinking and self-criticism. perfectionism can provoke anxiety and concerns for body image and weight, especially in...

this paper presents a new coding method for image compression based on jpeg2000 and contourlet transform. jpeg2000 standard is a common standard that uses discrete wavelet transform (dwt) in the compression process. the main problems of dwt are failure to detect curved edges in image and its shortage representation of the ridge and furrow patterns which cause deficiency and block artifacts rema...
