| 摘要 |
The invention relates to an apparatus (1) and a method for detecting entities in a numerical image (I), wherein said apparatus comprises computing means (11) configured for detecting, based on a histogram vector (V) determined on the basis of gradient and partitioning information, the presence of at least one of said entities in the image (I), signaling means (15) in signal communication with the computing means (11), and configured for being activated when said computing means (11) detect the presence of at least one of said entities in the image (I), memory means (12) containing partitioning information, and configured for allowing access to said partitioning information on the basis of said gradient information, wherein each piece of partitioning information identifies at least one of said partitioning elements that allow the computing means (11) to quantize said gradient information. |
