Post processing is importing image in software to enhance it for final publication - things like: removing noise, sharpening, removing unwanted elements and so on.
Image processing is the method of processing data in the form of an image. Image processing is not just the processing of image but also the processing of any data as an image. It provides security.
Image Processing classify as three type. (1) Low level image processing (noise removal, image sharpening, contrast enhancement) (2) Mid level image processing (segmentation) (3) High level image processing (analysis based on output of segmentation)
A kernel is defined as a small central part of something. In the case of image processing it is a tool used to edit the image by sharpening, blurring , embossing it, and so on.
Digital Image Processing is a type of Digital manipulation pertaining to pictures and video. "Photoshopping" a digital picture is an example of Digital Image Processing. Another example is what takes place in a digital camera when the image is captured on the image sensor and converted into a JPEG file to be saved on a memory card. Digital Signal Processing is a generic term for any manipulation of a Digitally encoded signal, such as Audio, Video, or Radio Signals. This also includes Digital Image Processing where there is a signal being sent from one part of a system to another, such as in a digital camera. There are Microprocessors that are specifically built to process digital signals known as "Digital Signal Processors" (or DSP's).
It is the creation of digital image, typically from a physical scene. The term assumed to imply or include processing,compression, storage, printing, and display of such image.
there are two types of image processing. 1.analog 2.digital.
Digital uses mega pixels ... vs film resolution is based on the area u have to record the image
Digital image is depending on the camera resolotion, where optical image depends on the quality of the film. Normally an optical image will be better then a digital image, unless you are using high end digital camera. I hope this helps, Icko www.rtgallery.com
please tell me ... which recent topics are going in digital image processing for research area .
The fundamental components of digital image processing are computer-based algorithms. Digital image processing allows a much wider range of algorithms to be applied to the input data and can avoid problems such as the build-up of noise and signal distortion during processing.
Without image acquisition you have no image to process.
