The Discrete Pulse Transform (DPT), a well known method for the analysis of signals, was recently extended to images. Here we propose an efficient algorithm generating DPT on a g...
In order to get an efficient image representation we introduce a new adaptive Haar wavelet transform, called Tetrolet Transform. Tetrolets are Haar-type wavelets whose supports ar...
This paper presents an inspection method of particle contamination for semiconductor reticles using continuous wavelet transform. Particle defect is considered as a singularity in...
A new color segmentation method is presented in this paper. The method is specified for color images that have both large and small objects, and objects with both step and ramp ed...
