TL;DR: In this article, a designed encryption algorithm is used for carrying out encryption through the following steps of: in a plurality of stored non-binary source operands, selecting a number by each source operand in sequence, and carrying out current bit operation on the selected numbers by adopting a random operation instruction until all the numbers of the plurality of source operators are selected to obtain a target operand; selecting a specific plaintext segment from each input biological characteristic by using an extraction operation rule in a private key.

TL;DR: In this article, a graphic image splicing fusion system is described, which consists of a graphics image acquisition module, a preprocessing module, an image pre-splicing module and a splicing effect preview module.

TL;DR: Zhang et al. as discussed by the authors extracted feature points from image edges after an image is preprocessed, then based on the feature points extracted from the image edges, reconstructing an accurate surface model; conducting accurate registration on the surface model and a series of color photos photographed of an object so as to obtain a 3D model; in accordance with RGB data and alpha channel data of the acquired 3d model, generating PNG format data of 3d models, and extracting the RGB data, and generating BMP format to be inserted to a video.

TL;DR: In this paper, a computer multimedia teaching device consisting of a bottom seat with a support rod and an operating body is arranged at the top of the support rod, the operating body was divided into a topic display area for displaying the topic of a to-be-written program, a code segment selecting area for providing code segments for user selecting, and a code editing area for editing codes.
