Abstract: An airflow sensing seat comprises a seat body (1), an airbag (2), a sensing assembly (3), and a micro control unit (4). The airbag (2) is provided in the seat body (1). A deformable support structure (21) is provided in the airbag (2). The support structure (21) is used to maintain an appropriate amount of gas in the airbag (2). A transmission mechanism (5) is provided between the airbag (2) and the sensing assembly (3). The transmission mechanism (5) is used to transmit gas disturbance in the airbag (2) to the sensing assembly (3). The sensing assembly (3) is used to generate a corresponding analog electrical signal according to the gas disturbance. The sensing assembly (3) is electrically connected to the micro control unit (4). The sensing assembly (3) transmits the analog electrical signal to the micro control unit (4). The micro control unit (4) is used to perform analysis and computation on the analog electrical signal so as to acquire a biological signal of a user.

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 of automatic photographs stitching in a photograph capturing electronic apparatus by capturing a photograph; on a viewfinder or display screen of said photograph capturing electronic apparatus, displaying at least one four-way guiding arrow for advising user the direction to move the photograph capturing electronic apparatus for capturing the next photograph which is suitable for stitching, the next suitable photograph having at a predetermined region, an area overlapped and aligned to the captured photograph with the overlapped and aligned area reaching a predetermined proportion; capturing the next suitable photograph; and stitching the consecutively captured photographs into a panoramic photograph.

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.
