摘要:
Disclosed is a moving object detection apparatus and method by using optical flow analysis. The apparatus includes four modules of image capturing, image aligning, pixel matching, and moving object detection. Plural images are successively inputted under a camera. Based on neighboring images, frame relationship on the neighboring images is estimated. With the frame relationship, a set of warping parameter is further estimated. Based on the wrapping parameter, the background areas of the neighboring images are aligned to obtain an aligned previous image. After the alignment, a corresponding motion vector for each pixel on the neighboring images is traced. The location in the scene of the moving object can be correctly determined by analyzing all the information generated from the optical flow.
摘要:
A method of making a semiconductor chip assembly includes providing a post, a base, a support layer and an underlayer, wherein the post extends above the base and the support layer is sandwiched between the base and the underlayer, mounting an adhesive on the base including inserting the post into an opening in the adhesive, mounting a conductive layer on the adhesive including aligning the post with an aperture in the conductive layer, then flowing the adhesive upward between the post and the conductive layer, solidifying the adhesive, then providing a conductive trace that includes a pad, a terminal and a selected portion of the conductive layer, providing a heat spreader that includes the post, the base, the underlayer and a thermal via that extends from the base through the support layer to the underlayer, then mounting a semiconductor device on the post, electrically connecting the semiconductor device to the conductive trace and thermally connecting the semiconductor device to the heat spreader.
