what is image in dip
Binary images are mostly used for general shape or outline.For Example: Optical Character Recognition (OCR).Binary images are generated using threshold operation.
Segmentation is the most difficult tasks in DIP.
The output is a raw pixel data which has all points of the region itself. And each color image has 24 bits/pixel means 8 bits for each of the three color band(RGB).8-bit color is used for storing image information in a computer's memory or in a file of an image. These coefficients can be removed without losing information. Whereas description is used for extracting information's to differentiate one class of objects from another.In this stage, the label is assigned to the object, which is based on descriptors.Knowledge is the last stage in DIP. And the system would perform some processing on the input image and gives its output as an processed image. It is a subfield of signals and systems but focus particularly on images. DIP focuses on developing a computer system that is able to perform processing on an image. Please mail your requirement at [email protected]. Only two colors that are black and white are found in it.
It is a process which takes a lot of time for the successful solution of imaging problems which requires objects to identify individually.Representation and description follow the output of the segmentation stage. The resulting image that is formed hence consist of only black and white color and thus can also be called as Black and White image.
Wide range of algorithms can be applied to input data which can avoid problems such as noise and signal distortion during processing. A normal grayscale image contains 8 bits/pixel data, which has 256 different grey levels.
It is also used to enhance the images, to get some important information from it. By doing this, the file size is reduced in the DCT domain. The color images contain gray level information in each spectral band.The images are represented as red, green and blue (RGB images). It is used for slow varying intensity images such as the background of a passport size photo can be represented as low-frequency components and the edges can be represented as high-frequency components.
Generally, in this stage, pre-processing such as scaling is done.Image enhancement is the simplest and most attractive area of DIP. It has 65,536 different color shades.
For example: Adobe Photoshop, MATLAB, etc. In the Fourier transform, the intensity of the image is transformed into frequency variation and then to the frequency domain. Initially, it was used by the UNIX operating system.The 16-bit color format is also known as high color format. Developed by JavaTpoint. To transform the raw data, representation is the only solution. Digital image processing has many advantages as compared to analog image processing. DCT is used for lossy compression. Generally, in this stage, pre-processing such as scaling is done.
