摘要： Methods and apparatus to determine the dimensions of a region of interest of a target object and a class of the target object from an image using target object landmarks are disclosed herein. An example method includes identifying a landmark of a target object in an image based on a match between the landmark and a template landmark; classifying a target object based on the identified landmark; projecting dimensions of the template landmark based on a location of the landmark in the image; and determining a region of interest based on the projected dimensions, the region of interest corresponding to text printed on the target object.

摘要： Digital video signature apparatus and methods for use with video program identification systems are disclosed. The example apparatus and methods generate a signature associated with a video program. An example system includes a frame scanner to scan video frames associated with the video program. The frame scanner is to select a video frame based on a number of intra-coded macro blocks within the video frame. The example system also includes an intra-coded macro block extractor to extract intra-coded macro blocks from the video frame and a scaled image extractor to extract a scaled image from the intra-coded macro blocks. A signature generator is also included in the example system to calculate a plurality of centroids associated with video frame based on the scaled image and to form the signature based on the plurality of centroids.
