What are the Basic steps of Image Processing System?
1. Image acquisition 2. Image restoration/enhancement 3. Image segmentation 4. Image interpretation
What is preprocessing in digital image processing?
The procedure done before processing by correcting image from different errors is preprocessing.this has to be done before image enhancement
Classification or types of image processing?
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)
What are the four major areas of computer operations in digital image processing?
The four major areas of computer operations in digital image processing is contrast enhancement. The second is remove the blur from pictures and smooth out graininess. The third would be magnifying, and rotating an image. Finally the image is compressed for storage.
Explain various steps in image processing?
1. Image acquisition is the first process. Generally the image acquisition stage involves preprocessing such as scaling.2. Image enhancement is among the simplest and most area. The idea behind enhancement techniques is to bring out detail that is obscured or simply to highlight certain features of interest in an image.3. Image restoration is ain area that also deals with improving the appearance of an image. Unlike enhancement, which is subjective, image restoration is objective. Image restoration techniques tend to be based on mathematical or probabilistic models of image degradation. Enhancement on the other hand, is based on human subjective preferences regarding what constitutes a good enhancement result4. Color image processing5. Wavelets are the foundation for representing images in various degrees of resolution.6. Compression deals with techniques for reducing the storage required to save an image or the bandwidth required to transmit it.7. Morphological processing deals with tools for extracting image components that are useful in the representation and description of shape.8. Segmentation procedures partition an image into its constituent parts or objects.9. Representation and description almost always follow the output of a segmentation stage, which usually is raw pixel data, constituting either the boundary of a region. Representation first deals with whether the data should be represented as a boundary or as a complete region. Choosing representation is only part of the solution for transformation raw data into a form suitable for subsequent computer processing. A method must also be specified for describe the data so that features of interest are highlighted. Description or feature slection deals with extracting attributes that result in some quantitative information of interest or are basic for differentiation one class of objects from another.10.
