Using this information, a cylindrical projection is used to map the 2D coordinates to a 2D image mosaic plane defined by the translation of the robot along the tunnel and the angle of rotation around the sensor axis. Central quadrilaterals are selected from individual images and pieced together ...

The invention discloses a method for adjusting a detection result of an image quadrilateral frame, comprising the following steps of: touching within the whole screen range through a mouse, a touch pen or a finger by using human-computer interface interactive technology after a target frame is ...
(e.g., triangle, quadrilateral, pentagon, and so on.) can be represented by a trivial combination of triangles (e.g., square ABCD is composed of triangles ABC and ABD, pentagon ABCDE is composed of triangles ABC, ACD, and ADE, and so on.), and the total luminosity of a square ...
7, and having relationship in which the pixel of interest is located inside a quadrilateral formed by drawing lines between the approximate centers of the areas. In any one of the first to sixth configurations, each frame of moving images may be picked up as the input image, and the ...
Get transformed images and predicted barcode bounding boxes generated by Dynamsoft Barcode SDK during the process of scanning barcodes.
This paper proposes a joint encryption and screen-cam robust watermarking scheme. This method combines the advantages of smartphone, encryption and watermarking technologies, thereby achieving watermark extraction with a smartphone, partial decryption an
[26] proposed a new model, named quadrilateral Markov random field (MRF), to compute spatial entropy for images (single-band) and spatial mutual information for two images (again, single-band), in which spatial redundancy is accounted for. To cope with both spectral and spatial redundancy, ...
A square when transformed using a Homography can change to any quadrilateral. In OpenCV an Affine transform is stored in a 2 x 3 sized matrix. Translation and Euclidean transforms are special cases of the Affine transform. In Translation, the rotation, scale and shear parameters are zero, ...
