What is use of filter in image processing?
Very many actions taken while processing images can be referred to as filtering. There are distortions and blurring and edge detection and color enhancements and all sorts of effects that fall under the "filtering" domain.
What are the differences between Image processing and computer vision?
§ Image processing tends to focus on 2D images, how to transform one image to another by pixel-wise operations, such as noise removal, edge detection, etc. whereas computer vision includes 3D analysis from 2D images. § As inferred from above, image processing does not require any assumptions, nor does it produce any interpretations about the image content, whereas computer vision often relies on more or less complex assumptions about the scene depicted in an image. § The output of image processing is another image whereas the output of computer vision is generally information in the form of a decision or data. § Image processing is a subset of computer vision.
What is prewitt filter?
prewitt filter is kind of edge detection and almost is better than many kind filter in edge detection ............. the code in matlab is: i=imread('cameraman.tif'); edge_p=edge(i,'prewitt');
What is City block distance in image processing?
the city block distance is the distance between two pixels. for example if we have two adjacent pixels their distance is 1 because they are adjacent. the this is used in edge detection applications
Image formed by an electron microscope is sharp at the centre and blurred in the edges Why so?
Two reasons. Firstly, charges (electrons in this case) congregate near edges (of the sample) will repel incoming electrons more so than a flat surface. Secondly, electrons hitting an edge are more likely reflected at an off angle away from the return-electron detector, weakening the intensity of the image there. ==============================
What does on edge mean?
This is an idiom meaning that someone is anxious or frustrated. The image is of them balancing on the edge of a mood. You use this phrase when you are worrying or irritated about something.
Where is the fuel filter on a 1996 Chrysler Town and Country?

What is a print ad that bleeds?
Any print ad where either the image or background color is extended to edge of the page is a bleed. Meaning the image is "bleeding" off the page.
