A method and an electronic apparatus for comparing tracking object are provided. The method applies an edge detection to a template image and a candidate image to generate a template edge image and a candidate edge image respectively. A vertical template edge image and a horizontal edge template image caused by summing (or averaging) the pixel values of the template image horizontally and vertically are used to compare with the summing (or averaging) pixel values of the horizontal/vertical candidate edge images. A measurement in the comparison is based on the positions of partial horizontal candidate edge image and the partial vertical candidate edge image. The method determines that a region of the candidate image has the tracking object according to the vertical coordinate information and the horizontal coordinate information.

Method and electronic apparatus for comparing tracking object

An image object tracking method and apparatus are provided. The image object tracking method includes the steps of: determining a feature point of a target object in a first frame, determining a prediction point of the feature point in a second frame, calculating an estimated rotation angle of an image capturing device according to a distance between the coordinate of the prediction point and the coordinate of the feature point and a distance between the image capturing device and the target object, calculating a lens rotation angle of the image capturing device rotated from a time point that the first frame is captured to a time point that the second frame is captured according to a piece of inertial measurement information provided by an inertial measurement unit, and determining whether the prediction point corresponds to the feature point by comparing the estimated rotation angle and the lens rotation angle.
