  2. Foreground detection - Wikipedia

    en.wikipedia.org/wiki/Foreground_detection

    Background subtraction is any technique which allows an image's foreground to be extracted for further processing (object recognition etc.). Many applications do not need to know everything about the evolution of movement in a video sequence, but only require the information of changes in the scene, because an image's regions of interest are ...

  3. Simple interactive object extraction - Wikipedia

    en.wikipedia.org/wiki/Simple_Interactive_Object...

    Simple interactive object extraction (SIOX) is an algorithm for extracting foreground objects from color images and videos with very little user interaction. [1] It has been implemented as "foreground selection" tool in the GIMP (since version 2.3.3), as part of the tracer tool in Inkscape (since 0.44pre3), and as function in ImageJ and Fiji (plug-in).

  4. Chroma key - Wikipedia

    en.wikipedia.org/wiki/Chroma_key

    Chroma key is achieved by comparing the phase of the video to the phase corresponding to the pre-selected colour. In-phase portions of the video are replaced by the alternate background video. [citation needed] In digital colour TV, colour is represented by three numbers (red, green, blue intensity levels). Chroma key is achieved by a simple ...

    en.wikipedia.org/wiki/Video_tracking

    Video tracking is the process of locating a moving object (or multiple objects) over time using a camera. It has a variety of uses, some of which are: human-computer interaction, security and surveillance, video communication and compression , augmented reality , traffic control, medical imaging [ 1 ] and video editing .

  6. Matte (filmmaking) - Wikipedia

    en.wikipedia.org/wiki/Matte_(filmmaking)

    For video transfers, transferring a "soft matte" film to a home video format with the full frame exposed, thus removing the mattes at the top and bottom, is referred to as an "open matte transfer." In contrast, transferring a "hard matte" film to a home video format with the theatrical mattes intact is referred to as a "closed matte transfer."

    Users can describe a story, and using Apple Intelligence, selects matching photos, videos, and music. Users can also remove distractions in images with the Clean Up tool in the Photos app. Apple Intelligence identifies background objects and removes them with a tap, brush, or circle.

  8. Object detection - Wikipedia

    en.wikipedia.org/wiki/Object_detection

    Objects detected with OpenCV's Deep Neural Network module (dnn) by using a YOLOv3 model trained on COCO dataset capable to detect objects of 80 common classes. Object detection is a computer technology related to computer vision and image processing that deals with detecting instances of semantic objects of a certain class (such as humans, buildings, or cars) in digital images and videos. [1]

  9. Moving object detection - Wikipedia

    en.wikipedia.org/wiki/Moving_object_detection

    Moving object detection is to recognize the physical movement of an object in a given place or region. [2] By acting segmentation among moving objects and stationary area or region, [3] the moving objects' motion can be tracked and thus analyzed later. To achieve this, consider a video is a structure built upon single frames, moving object ...
