Abstract: Provided is a method for plant improvement with the aim of increasing the light use efficiency of a plant. By expressing a light energy absorption and transduction (LEAT) protein in the plant, and by utilizing light energy absorbed to interact with a related methyl-quinone derivative in the plant body, such as plastoquinone, to catalyze water splitting and to release oxygen, the present invention increases the light use efficiency of the plant. The method effectively extends the utilization of light energy by the plant, thus increasing photosynthesis efficiency and yield.

Abstract: A method for merging first and second images includes determining a pixel difference image from the first and the second images, determining first and second locations of the foreground subject from the pixel difference image, determining a minimum path of values from the pixel difference image for a region between the first and the second locations of the foreground subject, forming a merged image by stitching the first and the second images along the minimum path, and adjusting pixels of the merged image within a width of the minimum path.

Abstract: A method is provided to automatically arrange scanned images so they can be stitched into a composite image. Initially the scanned images are reduced to low resolution and a gradient filter is applied. One scanned image is selected as a possible first image in a stitching order. The possible first image is rotated to one angle and correlated with remaining scanned images rotated to two corresponding angles. Only four scanned images that best correlate with the possible first image and pass a threshold are saved as possible second images in the order. The steps are repeated for subsequent places in the order and for the possible first image at other angles. The method is repeated for other possible first images to form other orders. At the end, a path through one of the orders that produces the best sum of correlation values is set as the correct stitching order.
