A method, computer system, and computer program product for determining a candidate patch for computer software is provided. According to a method, fingerprint(s) of patch(es) for a computer software is obtained first, wherein a fingerprint of a patch comprises function(s) being revised in the computer software if the patch is installed into the computer software. Then whether every function in the obtained fingerprint(s) of patch(es) has been called is monitored in response to beginning of execution of the computer software along to code path(s) related to bug(s). And at last candidate patch(es) is determined in response to end of the execution of the computer software along to the code path(s) related to the bug(s), wherein every function in the fingerprint of the candidate patch(es) has been called during the execution of the computer software.

A method of extracting a warehouse in a port from a hierarchically screened remote sensing image includes the following steps: first, recognizing a texture feature of a remote sensing image and extracting edge lines of a coast of a port; then, selecting a sample of an optional irregular texture region and forming, through a CA transformation, principal component images of different hierarchies by taking a ratio of a between-class difference to an intra-class difference being maximum as an optimization condition; sequentially, extracting a correlation relationship of the warehouse in the port, and forming a feature point set with recognized warehouses to be analyzed; and last, extracting a feature of a visually sensitive image through a scene image to obtain a feedback selection of a real scene image to extract the warehouse in the port accurately.
