MATLAB code of ROI detection and Hybrid image compression

Hello, friends today I would like to post one project in the field of image processing. The main objective of this project work is to detect the region of interest (ROI) by performing various simplest arithmetic operations that are used like morphological operations, segmentation operation. ROI is compressed with a lossless compression comparison technique. Perform lossy compression for the rest of the image. Wavelet-based methods will be used to compress the non ROI area of image i.e the rest of the image. Wavelet is one of the powerful tools used for image compression. JPEG 2000 uses a discrete wavelet transform (DWT) for compression. So, it is proposed to use DWT to compress non-ROI region.

MATLAB code of Lung cancer detection using Computer Aided System

Hello friends today i would like to post one project in the field of biomedical engineering/Biomedical image processing. The title of the project is Lung cancer detection using computer aided system. CANCER is one of the most serious health problems in the world field. The mortality rate of lung cancer is the highest among all other types of cancer. Lung cancer is one of the most serious cancers in the world, with the smallest survival rate after the diagnosis, with a gradual increase in the number of deaths every year. Survival from lung cancer is directly related to its growth at its detection time. The earlier the detection is, the higher the chances of successful treatment are. An estimated 85% of lung Cancer cases in males and 75% in females are caused by cigarette smoking.

MATLAB code of Image deblurring using Blind Deconvolution

Hello friends today I would like to post one project based on Image deblurring using blind deconvolution and PSF estimation. Most of the time we get blurred images from imaging sensor devices. So to improve the quality of such images image restoration plays the most important role. We get low-quality images by the following reasons.
-- Poor Illumination source.
-- Lack in a dynamic range of imaging sensors.
-- Wrong placing of aperture lens while image acquisition.
