The paper describes the study of combination of denoising and edge detection based on wavelet transform with design of treatment planning in radiotherapy.

Taking the advantage that the local linear projective algorithm (LLPA) does not have to know the dynamics of chaotic signals in advance, it uses this algorithm in the receiver end of Chaotic Shift Keying (CSK) system for the noise reduction.

Wavelet Analysis and Its Application in Denoising the Spectrum of Hyperspectral Image

A denoising and baseline correction method based on wavelet transform and their parameters choosing method were developed to remove noise and correct baseline in the spectrum effectively.

Image noise removal as the foundation of image segmentation and machine recognition is a classic field in image processing, and plays a very important role in the processing and analysis of medical images and satellite remote sensing image.
