Abstract: A method for calculating an object pick-and-place sequence and an electronic apparatus for automatic storage pick-and-place are provided. When a warehousing operation is to be performed, the following steps are performed. A weight of an object to be stocked that is to be put on a shelf is obtained. The weight is substituted into a plurality of coordinate positions corresponding to a plurality of unused grid positions respectively, so as to calculate a plurality of estimated center of gravity positions. Whether the estimated center of gravity positions are located within a balance standard area is determined so as to sieve out a plurality of candidate grid positions from these unused grid positions. One of the candidate grid positions is selected as a recommended position of the object to be stocked.

Abstract: One embodiment of the present invention provides a method and system for transforming a video bitstream in an interlaced format into a progressive format which can be displayed by a digital television. For example, the present embodiment utilizes the pixel information of a current field, previous field, and future field of the interlaced video bitstream to try to determine what the original content is of the missing lines of the current field. Specifically, the present embodiment utilizes different sets of pixel information in order to estimate the amount of motion that exist within a video bitstream. In this manner, the present embodiment is able to more closely determine the original value of the missing pixels of each field of the interlaced video bitstream. Therefore, the present embodiment provides a de-interlacing function enabling digital televisions to receive interlaced video bitstreams and display them in the progressive format.
