Abstract: The present invention provides an architectural exterior finish. The architectural exterior finish comprises: a plate-like base; a water-blocking unit formed at an upper end side of the base to prevent rainwater from leaking into a building; and side units formed on left and right sides of the base to come in surface contact with the building. The exterior of the building is finished by arranging a plurality of finishes continuously in all directions on a roof and an outer surface of the building such that construction is simplified to reduce construction time and construction costs. Moreover, since a fixed portion of a finish is covered by other overlaid finishes, it becomes difficult for moisture such as rainwater or snow to come into contact with the roof and the outer surface of the building, thereby extending the durability of the finish. In addition, the water-blocking unit is formed on the upper side of the base by comprising a horizontal piece bending along a horizontal line, a vertical piece bending along a vertical line from the horizontal piece, and rain-receiving wings bending around the vertical line as an axis from the left and right of the vertical piece. Therefore, the present invention allows for mass production of architectural exterior finishes as products and easy handling by ordinary technicians during installation, and enhances the aesthetic appearance of the building's exterior to contribute to environmental improvement. Furthermore, it is possible to improve the function of preventing rainwater infiltration by preparing means to block the entry of rainwater through joints of the finishes.

Abstract: The present invention relates to an image processing method, a device, electronic equipment, and a readable recording medium, which relates to the field of computer vision technology. According to the present invention, each single image buffer queue is maintained using a face recognition module and a work processing module. In other words, the face recognition module maintains the face image buffer queue of a face image and the work processing module maintains the background image buffer queue of a background image, that is, a first image. Since the face recognition module maintains only the face image buffer queue, simply the determined optimal face image, that is, a face image to be matched needs to be transmitted to the work processing module. In the background image buffer queue maintained by the work processing module, the work processing module matches the background image matched to the optimal face image transmitted by the face recognition module, and thus image recognition processing and image matching processing can be performed with respect to a face on a video source.
