Image processing

This is the 1st post of blog post series ‘Image Processing’.

Introduction to Digital Image Processing

Digital Image Processing means processing digital image by means of a digital computer. We can also say that it is a use of computer algorithms, in order to get enhanced image either to extract some useful information.

Technical Def: An image is defined as a two-dimensional function,F(x,y), where x and y are spatial coordinates, and the a_mplitude of F_ at any pair of coordinates (x,y) is called the intensity of that image at that point. When x,y, and amplitude values of F are finite, we call it a digital image.

Types of an image

1. Binary Image as its name suggests, contain only two pixel elements i.e 0 & 1,where 0 refers to black and 1 refers to white. This image is also known as Monochrome.

2. Black and White Image which consist of only black and white color is called Black and White Image.

3. 8 bit Color Format is the most famous image format.It has 256 different shades of colors in it and commonly known as Grayscale Image. In this format,0 stands for Black, and 255 stands for white, and 127 stands for gray.

4. 16 bit Color Format is a color image format. It has 65,536 different colors in it.It is also known as High Color Format. In this format the distribution of color is not as same as Grayscale image.

A 16 bit format is actually divided into three further formats which are Red, Green and Blue. That famous RGB format.

The remaining tasks will be in 2nd post out soon.
