The ninth item of Wikipedia’s policy for non-free content states that non-free images should only be used in the article namespace (not disambiguation pages), and goes further into the underlying reasons for the policy. This issue is important because copyright complaints are a very direct way in which Wikipedia could be financially harmed.
All detection techniques are based on modelling the background of the image, i.e. set the background and detect which changes occur. Defining the background can be very difficult when it contains shapes, shadows, and moving objects. In defining the background, it is assumed that the stationary objects could vary in color and intensity over time.
This is a category of articles relating to software which can be freely used, copied, studied, modified, and redistributed by everyone that obtains a copy: "free software" or "open-source software". Typically, this means software which is distributed with a free software license , and whose source code is available to anyone who receives a copy ...
Detection and labeling of the different zones (or blocks) as text body, illustrations, math symbols, and tables embedded in a document is called geometric layout analysis. [2] But text zones play different logical roles inside the document (titles, captions, footnotes, etc.) and this kind of semantic labeling is the scope of the logical layout ...
First the background is captured without actors or other foreground elements; then the scene is recorded. The image of the background is used to cancel the background in the actual footage; for example in a digital image, each pixel will have a different chroma key. This is sometimes referred to as a difference matte. [17]
The concept of substituting a pink version of something for the original color was borrowed from The Pink Phink, wherein the Little Man is trying to paint a house blue but the Panther prefers pink paint.
On second thought, I struck part of my reply above. Per FPC instructions, images are judged at full size, not at thumbnail or at full screen. So I don't see anything wrong with the font size and the layout. For instance we have lots of map FPs which are busier and less legible than the nom image when viewed at thumbnail or full screen.
The process of Canny edge detection algorithm can be broken down to five different steps: Apply Gaussian filter to smooth the image in order to remove the noise; Find the intensity gradients of the image
