Image denoising in wavelet and spatial domain
The goal of any de-noising technique is to remove noise from an image which is the first step in any image processing. The noise removal method should be applied watchful manner otherwise artefacts can be introduced which ... -
LMMSE-based low complexity image denoising in non-uniform directional filter bank
This dissertation is about creating a non-redundant, effective and low-complexity denoising method. Denoising an image involves removing noise from an image to keep the original elements of the image and remove unwanted ... -
Performance analysis of two dimensional wavelength/time OCDMA system for optical network
The major interference factor in an Optical Code-Division Multiple-Access System (OCDMA) is the noise in the form of Multiple Access Interference (MAI), which induces the occurrence of Bit Error Rate (BER). Phase Induced ... -
Speech enhancement hybrid of wiener filter and haar wavelet algorithm using DSP
The most common, natural and effective form of communication between human is speech. Generally, during speech communication a lot of unwanted noise were corrupted and make speech signal weak. Due to this enhancing or ...
