PPT-Bitmap Image Vectorization using Potrace Algorithm

Graduation Project Graphics Editor Reference Potrace a polygonbased tracing algorithm Peter Selinger September 20 2003 ABSTRACT Our project Vectorization rastertovector conversion consists of analyzing a raster image to convert its pixels representation to a vector representation The basic assumption is that such a vector representation is more suitable for further interpretation of the image to get an image larger or smaller than the Real size without any loss in quality like a digital image. Shabana Kazi. Introduction. A bitmap index is a special kind of index that stores the bulk of its data as bit arrays (commonly called "bitmaps").. A bitmap index for a field F is a collection of bit-vectors of length n. . CSc. 2010. Spring 2011. Marco Valero. Overview. Review image basics. Making pictures. Image processing.

The relevant features for the examination task are enhanced. The irrelevant features for the examination task are removed/reduced. Here the input and output image are both digital image in color or gray scale.. Algorithm is a step-by-step procedure, which defines a set of instructions to be executed in a certain order to get the desired output. Algorithms are generally created independent of underlying languages, i.e. an algorithm can be implemented in more than one programming language.. Complete the worksheet quiz on bitmap images.. 2. Objective of the . sesson. Understand how computers store bitmap images.. Explain how files are saved in bitmaps and how size and colour depth can affect the file size of an image..
