A sketch colored digitally with use of several different blend modes in order to preserve the pencil lines and paper texture below the color layers. Blend modes (alternatively blending modes [ 1 ] or mixing modes [ 2 ] ) in digital image editing and computer graphics are used to determine how two layers are blended with each other.
Corner detection is an approach used within computer vision systems to extract certain kinds of features and infer the contents of an image. Corner detection is frequently used in motion detection, image registration, video tracking, image mosaicing, panorama stitching, 3D reconstruction and object recognition.
The idea is simple: look at the differences between a pair of images. Assuming the object of interest is moving, the difference will be exactly that object. Improving on this idea, Kenney et al. proposed interactive segmentation . They use a robot to poke objects in order to generate the motion signal necessary for motion-based segmentation.
Among the first distinct sections of the canvas to emerge was a corner of entirely blue pixels (named "Blue Corner") and an homage to Pokémon. [16] As the canvas developed, some established subreddit communities, such as those for video games , sports teams and individual countries, coordinated their user efforts to claim and decorate ...

Some polygons of different kinds: open (excluding its boundary), boundary only (excluding interior), closed (including both boundary and interior), and self-intersecting. In geometry, a polygon (/ ˈ p ɒ l ɪ ɡ ɒ n /) is a plane figure made up of line segments connected to form a closed polygonal chain.
A vertex of an angle is the endpoint where two lines or rays come together. In geometry, a vertex (pl.: vertices or vertexes) is a point where two or more curves, lines, or edges meet or intersect.
Right triangle, with the right angle shown via a small square Another option of diagrammatically indicating a right angle, using an angle curve and a small dot. In Unicode, the symbol for a right angle is U+221F ∟ RIGHT ANGLE (∟). It should not be confused with the similarly shaped symbol U+231E ⌞ BOTTOM LEFT CORNER (&dlcorn ...
