One of the simpler ways of increasing the size, replacing every pixel with a number of pixels of the same color. The resulting image is larger than the original, and preserves all the original detail, but has (possibly undesirable) jaggedness. The diagonal lines of the "W", for example, now show the "stairway" shape characteristic of nearest ...
Any or none of these options may be specified to control the size of the image. In the case of images with captions, if the image is already smaller than the requested size, then the image retains its original size (it is not enlarged). In the case of images without captions, the image will be enlarged or reduced to match the requested size.

Then the position, orientation and size of the virtual object are defined relative to the coordinate frame of the recovered model. For online match moving , SIFT features again are extracted from the current video frame and matched to the features already computed for the world model, resulting in a set of 2D-to-3D correspondences.
An image scaled with nearest-neighbor scaling (left) and 2×SaI scaling (right) In computer graphics and digital imaging, image scaling refers to the resizing of a digital image. In video technology, the magnification of digital material is known as upscaling or resolution enhancement.
size Size to display image, in pixels. Use is discouraged per WP:THUMBSIZE; see |upright= below instead. maxsize Maximum size to display image. Note: If no size or sizedefault params specified then image will be shown at maxsize. sizedefault The size to use for the image if no size param is specified. Defaults to frameless. alt Alt text for the ...
3D projections use the primary qualities of an object's basic shape to create a map of points, that are then connected to one another to create a visual element. The result is a graphic that contains conceptual properties to interpret the figure or image as not actually flat (2D), but rather, as a solid object (3D) being viewed on a 2D display.
State-of-the-art object detectors allow only the fixed size of image and change the input image size according to it. This change may deform the small objects in the image. The tiling approach [ 21 ] helps when an image has a high resolution than the model's fixed input size; instead of scaling it down, the image is broken down into tiles and ...
