An optical image stabilizer (OIS, IS, or OS) is a mechanism used in still or video cameras that stabilizes the recorded image by varying the optical path to the sensor. This technology is implemented in the lens itself, as distinct from in-body image stabilization ( IBIS ), which operates by moving the sensor as the final element in the optical ...
Digital image correlation and tracking is an optical method that employs tracking and image registration techniques for accurate 2D and 3D measurements of changes in images. This method is often used to measure full-field displacement and strains , and it is widely applied in many areas of science and engineering.
A type of neutral density filter in which brightness is reduced more on one side of the filter than on the other, allowing the photographer to reduce the contrast between, for example, bright sky and dark land. HDR: High dynamic range. Techniques that allow a digital image to show a wider contrast range than current image sensors can record in ...
The following is a simplistic illustrated explanation of how motion compensation works. Two successive frames were captured from the movie Elephants Dream.As can be seen from the images, the bottom (motion compensated) difference between two frames contains significantly less detail than the prior images, and thus compresses much better than the rest.
Image analysis or imagery analysis is the extraction of meaningful information from images; mainly from digital images by means of digital image processing techniques. [1] Image analysis tasks can be as simple as reading bar coded tags or as sophisticated as identifying a person from their face .
Video content analysis is a subset of computer vision and thereby of artificial intelligence. Two major academic benchmark initiatives are TRECVID , [ 23 ] which uses a small portion of i-LIDS video footage, and the PETS Benchmark Data. [ 24 ]
Image stitching is widely used in modern applications, such as the following: Document mosaicing [5] Image stabilization feature in camcorders that use frame-rate image alignment; High-resolution image mosaics in digital maps and satellite imagery; Medical imaging; Multiple-image super-resolution imaging; Video stitching [6] Object insertion
SteadyShot is the trademarked name of the integrated image stabilisation technologies used in Sony video camcorders, DSLR cameras, mirrorless cameras and on Sony Xperia smartphones and tablets. Different versions of these technologies are known as Super SteadyShot (SSS) in Sony's Cyber-shot product line, in addition to SteadyShot INSIDE (SSI ...
