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.
The Average (mean) filter smooths image data, thus eliminating noise. This filter performs spatial filtering on each individual pixel in an image using the grey level values i…n a square or rectangular window surrounding each pixel. For example: a1 a2 a3 a4 a5 a6 3x3 filter window a7 a8 a9 The average filter computes the sum of all pixels in the filter window and then divides the sum by the number of pixels in the filter window: Filtered pixel = (a1 + a2 + a3 + a4 ... + a9) / 9
Digital uses mega pixels ... vs film resolution is based on the area u have to record the image
Easy to manipulate. Compact storage. (those are also the disadvantages)
Disvantages: 1) It's very costly depending on the system used, the number of detectors purchased. 2) Time consuming 3) Lack of qualified professional
The procedure done before processing by correcting image from different errors is preprocessing.this has to be done before image enhancement
four typesof images are there- binary,grayscale,indexed and truecolor
It is the processing (changing) of color images using a computer.
Digital image processing is great because you can save a file digitally and it can be uploaded in a matter of seconds. A disadvantage is that some may edit their photos in…stead of taking high quality photographs.
Noise is static, kinda like when your tv screwes up
gamma img processing,uv imaging,visible imaging,microband wave imaging etc etc
Dither is an intentionally applied form of noise used to randomize quantization error, preventing large-scale patterns such as color banding in images. Dither is routinely use…d in processing of both digital audio and digital video data, and is often one of the last stages of audio production to compact disc
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….
Lot's of photographers use digital image processing as opposed to old fashioned because you can do non-destructive editing and come back at a later time and make changes. Usin…g the old fashioned way of editing (using film and chemicals), if you ie. overexpose part of the image, or remove an element, you are stuck with the changes you made.
A filter is an effect that can be added to an image that affects the overall appearance, or apearance of a selected area, of an image.
Image Enhancement is trying to improvise the quality of image over received or initial image.It is a subjective process. Meaning it varies from person to person to what extent… the quality has to be fined to. Techniques involved are- 1. POINT PROCESSING. A IMAGE NEGATION B LOG COMPRESSION C CONTRAST STRETCHING D GREY LEVEL SLICING(WITH OR W/O BACKGROUND CONSERVATION) E BIT PLANE SLICING 2. NEIGHBORHOOD PROCESSING A HISTOGRAM EQUALIZATION B HISTOGRAM SPECIFICATION
Post processing is importing image in software to enhance it for final publication - things like: removing noise, sharpening, removing unwanted elements and so on.
