  • Method and device for detecting an object in an image
    Patent number: 9147115
    Abstract: A method for detecting at least one object in an image including a pixel array, by means of an image processing device, including searching out the silhouette of the object in the image only if pixels of the image are at the minimum or maximum level.
    Type: Grant
    Filed: April 16, 2013
    Date of Patent: September 29, 2015
    Assignee: STMICROELECTRONICS (GRENOBLE 2) SAS

  • Object detection in an image
    Patent number: 8805081
    Abstract: The invention concerns a method of performing, by an image processing device, object detection in an image comprising: performing one or more tests of a test sequence for detection of a first object on pixels values of a plurality of at least partially overlapping sub-regions (310, 312, 314) of a first search window (108); generating a cumulative score based on results of said one or more tests on said plurality of sub-regions; comparing said cumulative score with a threshold value; and based on said comparison, selectively performing one or more of said tests of said test sequence on at least one further sub-region of said first search window, said at least one further sub-region at least partially overlapping each of said plurality of sub-regions.
    Type: Grant

  • Method and Device for Detecting an Object in an Image
    Publication number: 20130266177
    Abstract: A method for detecting an object in an image by means of an image processing device, includes several steps of object search in the image at different search scales. During at least one of the search steps, portions of the image are excluded from the search. The size of the portions decreases as the search scale increases.
