TL;DR: In this paper, a binary code division multiple access wireless image data sending and receiving method is proposed, which is based on the idea of using a small-unit B-CDMA frame structure packets.
Abstract: The present invention relates to a binary code division multiple access wireless image data sending and receiving method, comprising: (a) a step in which a terminal that provides images receives an image request signal from another terminal; (b) a step of extracting and analysing related information that will be used in editing the image to be transmitted from the image request signal; (c) an image conversion step in which the output image is converted into a format that can be received by the wireless terminal; (d) a step of reconfiguring the image-converted information into small-unit B-CDMA frame structure packets; (e) a transmission step in which the reconfigured packet information is transmitted to a user's terminal; and (f) an image-restoring step in which the packet information is received by the terminal and the image in the packets so received is restored to the full image size. When the present invention of this type is employed, sending and receiving can be carried out in the form of packet data having a frame structure specifically for B-CDMA, and consequently it is possible to reduce header volume as compared with transmissions comprising IP headers and MAC headers of the prior art, and it is possible to use wireless spaces more efficiently and hence it is possible to improve the transmission efficiency of IP solutions.

TL;DR: In this paper, an image processing method comprises the steps of obtaining a to-be-processed 2D image, obtaining a texture depth map of the image according to the texture features of the 2D images, and dividing the image into a foreground area and a background area.
Abstract: The invention discloses an image processing method and device, a computer readable storage medium and equipment The image processing method comprises the steps of obtaining a to-be-processed 2D image; obtaining a texture depth map of the 2D image according to the texture features of the 2D image; dividing the 2D image into a foreground area and a background area; obtaining a motion depth map of the foreground area and a linear depth map of the background area; fusing the motion depth map and the texture depth map to obtain a foreground depth map, and fusing the linear depth map and the texture depth map to obtain a background depth map; fusing the foreground depth map and the background depth map to obtain a depth map of the 2D image; and fusing the 2D image and the depth map of the 2D image to obtain an image with stereoscopic impression Compared with a previous single depth value extraction method, the method for comprehensively extracting the depth value has the advantages that the obtained depth value is more accurate and higher in precision, so that the effect is better when the 2D image is converted into the 3D image or a VR image

TL;DR: In this paper, an information processing system includes a conversion processing device for generating data of the converted image by applying the image conversion processing to original image data, in which a plurality of images were overlapped on each other or the images are overlapped by being continuously deviated by the amount of a predetermined size by a mathematical procedure determined in advance based on a repairable condition.
Abstract: PROBLEM TO BE SOLVED: To provide an image conversion method in which, using the mathematically guaranteed means for preventing credibility as an image of data from being damaged while reducing the amount of image data, image data having confidentiality, by chance, prevents the possibility of being intercepted and altered by a third party, and also to provide an inverse conversion method thereof.SOLUTION: An information processing system includes: a conversion processing device for generating data of the converted image by applying the image conversion processing to original image data, in which a plurality of images are overlapped on each other or the images are overlapped by being continuously deviated by the amount of a predetermined size by a mathematical procedure determined in advance based on a repairable condition; and an inverse conversion processing device for executing the image inverse conversion processing which restores the converted image data to the original image by the mathematic procedure determined in advance based on the repairable condition.SELECTED DRAWING: Figure 1

03 Oct 2019TL;DR: In this paper, a visual guidance display control unit is used to guide a movement from a predetermined position to a different position. But it is not suitable for the use of cameras.
Abstract: A visual guidance device including: an image data acquisition unit which acquires image data when a machine is seen from a predetermined position and image data when the machine is seen from a different position from the predetermined position; an image conversion unit which produces image data by converting, with one or more aspect ratios, the image data when the machine is imaged from the predetermined position; and a guidance display control unit which sequentially displays, on a display unit, the image data when the machine is imaged from the predetermined position, the image data produced by the image conversion unit and the image data when the machine is imaged from the different position so as to guide a movement from the predetermined position to the different position.
