Comparison of Citrus Fruit Surface Defect Classification using Discrete Wavelet Transform, Stationary Wavelet Transform and Wavelet Packet Transform Based Features

The aim of this study is to classify the citrus fruit images based on the external defect using the features extracted in the spectral domain (transform based) and to compare the performance of each of the feature set. Automatic classification of agricultural produce by machine vision technology plays a very important role as it improves the quality of grading. Multi resolution analysis using w...

Adaptive Video Denoising Using Discrete Wavelet Transform

This paper proposes a spatial video de-noising method based on adaptive filtering and temporal filtering as it requires less computation time and suitable for real-time applications. video de-noising rely on spatial adaptive temporal filtering is offered. Initially in the adaptive spatial filtering, DWT (discrete wavelet transfer) is applied on all frame. These co-efficient are used to alter tr...

Steganography Technique to Hide a Video into Another One via Discrete Wavelet Transform

In this work an algorithm is proposed to hide information, into an .avi video file. Such file is separated in audio and video. The video breaks down in its frames, in which we apply a discrete wavelet transform. Once the image has been separated in frequencies, zones are chosen where the information can be hidden. In this work the source of information is an image. Nevertheless, the procedure c...
