Images and videos transmitted across communication channels may contain noise artefacts or other degradations that result from poor communication caused by noisy channels. In these application domains, image restoration has consistently been important to enhance visual quality as well as to increase the performance of subsequent activities, like analysis and interpretation. This study used a variety of imaging techniques, including MRI, CT, and ultrasonic pictures of the human abdomen. The Mean Absolute Difference (MAD) of nearby pixels is used to estimate noisy pixels. The handling window's median of uncorrupted pixels is used to swap out the noisy pixels that were found. By generating the internal covariance matrix with the help of the Extended Kalman Filter and utilising the Gray Wolf Optimization approach for parameter optimization, the recognition is prepared for some variations occurring in the time sequence.

Air pollution is predominately emitted through the exhaust of motor (both light duty and heavy duty) vehicles and the combustion of fossil fuels. Pollution control is playing a important role to control the upcoming generation and noxious emissions like CO, NOX, HC and soot (particulates). Aim of this research study is to diminish the emissions from the automobiles through design and manufacturing of nano catalytic converter by replacing the offered costly metals such as Platinum. Nano Materials like nano Rhodium and nano Palladium were obtained by using chemical vapour deposition (CVD) method. The obtained nano powder was deposited in the honey comb formation structure. By using the nano catalytic converter the pollution is reduced in a marginal level.
