1. State the properties of Holographic images?
Holographic images are not clear diagrams 3-dimensional can also be recorded on materials other than photographic plates records intensity of light and phase created by coherent light using a laser beam
2. Define Fractals?
Fractals are regular objects with a high degree of irregular shapes. It is a lossy compression technique but it doesn’t change the shape of the image. Fractals are decompressed images that result from a compression format
3. Explain Fractal Compression?
Fractal Compression is based on image content i.e., it is based on similarity of patterns within an image. The steps in Fractal compression are a digitized image is broken into segments the individual segments are checked against a library of fractals the library contains a compact set of numbers called iterated function these system codes will reproduce the corresponding fractal
4. State the applications of Document Imaging?
Document Imaging is used in organizations such as Insurance agencies Law offices Country and State Governments Federal Government Department of Defence (DOD)
5. Define Compression Efficiency?
Compression Efficiency is defined as the ratio in bytes of an uncompressed image to the same image after compression.
6. What is Image Processing?
Image Processing refers to processing a digital image using a digital computer. An image processing system will alter the contents of the image. It involves Image Recognition, Image Enhancement, Image Synthesis and Image Reconstruction.
7. Explain Image Calibration?
The overall image density is calibrated. In Image calibration the image pixels are adjusted to a predefined level.
8. What is Grayscale Normalization?
The overall grayscale of an image or picture is evaluated to determine if it is skewed in one direction and if it needs correction.
9. What is Frame Averaging?
The intensity level of the frame is averaged to overcome the effects of very dark or very light areas by adjusting the middle tones.
10. What is Image Animation?
Images are displayed sequentially at controlled display speeds to provide image animation. Image Animation is the basic concept of displaying successive images at short intervals to give the perception of motion. Image Animation is a technology developed by Walt Disney and brought to every home in the form of cartoons.
11. How Image Annotation is done?
Image Annotation can be performed in two ways as a text file stored along the image. as a small image stored with the original image.
