This document summarizes a course on embedded systems presented by Md Nazmul Hossain Mir to Sraboni Dhar. The course code is CSE 423 and name is Embedded System. It discusses biomedical image processing, which involves gathering biomedical signals, image formation, processing pictures, and image display for medical diagnosis by extracting features from images. It also discusses the need for image processing in medicine such as changing density ranges, restoring images, registering multiple images, constructing 3D images, and removing artifacts. Finally, it covers the main areas of image processing which are image formation, visualization, analyzing images, and managing acquired information.

2. Biomedical Image Processing
Biomedical image processing is a very broad field; it
covers biomedical signal gathering, image forming,
picture processing, and image display
to medical diagnosis based on features extracted
from images.

3. NEED OF IMAGE
PROCESSING IN MEDICINE
• Changing density dynamic range of B/W images.
• Restoration and smoothing of images.
• Registration of multiple images and creating mosaic of multiple images.
• Construction of 3-D images from 2-D images.
• Generation of negative images.
• Removal of artifacts from the image.
• It has also helped doctors to make keyhole surgeries without opening too
much of the body.

4. Types Of Images
1.Analog image:
• An analog image is described by the spatial distribution of brightness or
gray levels that reflect a distribution of detected energy.
• The image can be displayed using a medium such as paper or film.
2.Digital image:
• A digital image is discrete in both spatial and intensity (gray level)
domains
• A discrete spatial location of finite size with a discrete gray-level value is
called a pixel.

5. Image processing covers
Image processing covers four main areas:
Image formation.
Visualization
Analysis of image.
Management of the acquired information.
