Raser to VectorGet a behind-the-scenes understanding of the science and mathematics required for software to convert raster images to vector.
Vectorization changes the characteristics of a raster image, which is made up of pixels. Vectorization transforms these pixels into coordinates in a process that is prone to introducing errors and mistakes. The errors and mistakes form the basis of the measurement of the conversion system’s performance as detailed in the study titled Using local deviations […]
A raster to vector conversion (vectorization) aims to fulfill two objectives. The first entails converting paper-based line drawings into CAD-formatted numeric data that can be reused. The second is to enable pre-processing in order to make symbols much more pronounced such that there’s somewhat of a match between the output and input images. The conversion […]
Floorplans begin their lifecycle as vector files since designers and architects usually produce architectural floorplans using Sketchup, HomeStyler, and AutoCAD, which are vector-based applications. However, incorporating clients’ input in the design and approval process requires the rasterization of these vector files by printing or publishing them. The Motivation for the Study While the prints help […]
Fernando Silva-Coira and friends make great strides, by developing algorithms that accept both raster and vector inputs – a first, in their research article titled Efficient processing of raster and vector data. Through their efforts, the authors solve an issue that was so problematic that it had been ‘shunned’ by researchers in previous studies. In […]
You may have noticed that some raster images appear sharper than others and are less pixelated when zoomed in at the same level. This is as a result of the difference in resolution, as raster images are resolution-dependent. The resolution of an image is what determines its clarity and quality. Resolution is the number of […]
The rasterization of vector files or the vectorization of raster files is common, particularly when dealing with geographical information systems (GIS). However, the conversion process gives rise to accuracy concerns, which have, in turn, been the subject of multiple research studies. Russell Congalton, in his research ‘Exploring and Evaluating the Consequences of Vector-to-Raster and Raster-to-Vector […]
The applications of raster and vector images transcend the usual CAD drawings (such as converting PDF files to CAD), GIS maps, photography, and graphic designs. Simply put, raster and vector uses are extensive. As Gal, Lindberg, and Unger sought to find out in their 2009 research paper titled Computing continuous sky view factors using 3D […]
Raw, lossless files are quite sizable, an issue that becomes problematic when archiving because a lot of storage space is needed. Now, picture yourself in the late 20th century in a world with slow internet, small-capacity storage devices, and slow computers. It’s unfathomable, isn’t it? But this was the life for technology enthusiasts then. The […]
Unbeknown to you, you may have drawn Bezier curves while growing up. Perhaps because the process was fascinating or the result was spectacularly beautiful. All you needed then was a pen/pencil, blank paper, and a ruler. You first drew two lines, that were either perpendicular or at an angle, and subsequently marked equidistant points along […]
