formula to find compression ratio when bits per pixel is given
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
because in fractal coding you save Coefficients of image blocks instead of values of block pixels. decoding starts from initial image and Coefficients applied on it. so the initial image can have any resolution
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
That very much depends on the format the images are stored in and what quality the images are as well. For example, a 6 mega pixel image will be about 3.2 mb in size assuming decent image compression such as JPG format. However most good digital camera can also capture images as TIFF (targas image file format) which is a bitmap. This means there is no compression at all in the imagine and it's saved pixel per pixel exactly as the camera sees it. The imagine might be 10, 15 and even 20 mb an image in that case. Your camera will give you an estimate when you put the card into it and select image quality in the menu. Hope that helps!
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.
