Image processing involves various operations on images. An image is a collection of pixels. Each pixel has its position and resolution.
a pixel is the smallest element in an electronic image
Bitmap image is raster or pixel based image. Bitmap image is made up of pixels, every pixel in grid have its own position and color. Pixels are mapped to the pixel grid, that's why its name is Bitmap.
its store 1bit per pixel
Pixel
A pixel is one dot in the image. A 10 megapixel camera will have 10 million pixels that make up the image.
Pixel Pitch is the measurement of the smallest bit of data in a video image. The smaller the size of the pixels in an image, the greater the resolution.

as a simple example assume you want divide a gray level secret image to two shares. Each pixel in the secret image is expanded to four subpixels in each share that consist of white and black so width and height of shares is twice of secret image. first share is an image wich has random pixels of black or white with equal probability. in second share, if corresponding pixel in main secret image is white then the pixel in second share is the same as first share and if pixel in the secret image is black, corresponding pixel in second share would be inverse of the same pixel in first share.
Image Processing is area in which image is processed based on pixel (spatial) and frequency methods. In spatial method pixel value are subject to change For more details on image processing research visit http://imageprocessing.webs.com/
