Abstract:
A method of detecting image movement is provided. A reference frame is accessed, and a reference window is captured from the reference frame. A sampling frame is then accessed. When the reference window has not reached the margin of the reference frame, a new window is captured from the reference frame to replace the reference window. From the reference frame, a window matching the reference window is searched and a moving vector is calculated. When the sampling window reaches the margin of the sampling frame, the sampling frame replaces the reference frame. Another reference window is also captured from the reference frame, and the step of accessing the sampling frame is repeated.
Abstract:
An optimal correlation matching method for determining track behavior, which applies a video stream having a first image and a second image for locating a motion vector associated with a block of the first image in the second image, wherein each image has a plurality of blocks in rows and columns and each block has a plurality of pixels in rows and columns. The method divides a search window into a plurality of search subdivisions, selects one from the subdivisions as an operating search window, locates a center of a block respectively at all positions of the operating search window such that upon each position of the center located, pixels of the block of the first image in accordance with the operating search window are applied to corresponding pixels of the second image for performing match operation, thereby reducing required number for match operation.

Abstract:
A system and method for automated sorter operations including a storage device and a sorting module. The storage device stores multiple process records, each record including an identity and a current status. The sorting module receives a wafer lot identity and acquires the current status from the process record accordingly. The sorting module issues a first status setting instruction to a manufacturing execution system (MES) to release the wafer lot, issues a flow instruction with sorting recipes directing the MES to perform a sorter operation, and issues a second status setting Instruction to the MES to hold or bank the wafer lot.
