Anatomical global spatial normalization (aGSN) is presented as a method to scale high-resolution brain images to control for variability in brain size without altering the mean size of other brain structures. Two types of mean preserving scaling methods were investigated, “shape preserving” and “shape standardizing”. aGSN was tested by examining 56 brain structures from an adult brain atlas of 40...
Nowadays, many traditional approaches which encrypt multimedia data directly are not suitable for the special nature of multimedia data. So many new encryption approaches have merged to overcome shortcomings and provide confidentiality. But the file size increases after encryption. The objective of our work is to keep the file size for JPEG image after encryption and do not affect the signal processing...
In size preserving video tracking, the camera's focal length (zoom) is adjusted automatically to compensate for the changes in the target's image size caused by the relative motion between the camera and the target. The accurate estimation of these changes is paramount to the system performance. Structure from motion (SFM) based on the weak perspective projection model has been applied to real time...
