In this paper, we investigated the use of two Kinects for capturing the 3-D model of a large scene. Traditionally the method of utilising one Kinect is used to slide across the area, and a full 3-D model is obtained. However, this approach requires the scene with a significant number of prominent features and careful handling of the device. To tackle the problem we mounted two back-to-back Kine...

We consider the subgroup of the abelian sandpile group of the grid graph consisting of configurations of sand that are symmetric with respect to central vertical and horizontal axes. We show that the size of this group is (i) the number of domino tilings of a corresponding weighted rectangular checkerboard; (ii) a product of special values of Chebyshev polynomials; and (iii) a double-product wh...

This study investigated the effects of the stimulus size on the spatial frequency tuning of the Ouchi illusion, which is an illusory sliding motion perceived in a checkerboard pattern of rectangular elements that is surrounded by a checkerboard pattern of orthogonally oriented elements. Two experiments were conducted to measure the perceived strength of illusion. The optimal size of the inner p...

Earlier there are different interpolation techniques for denoising of images. When an image is zoomed checkerboard effect/ringing arises in images. In order to remove interpolation artefacts such as image blur and checkerboard effect. The proposed technique “DIRETIONAL DENOISE SCHEME” tries to amend the interpolation error. Meanwhile edge preservation is a critical issue in both image denoising...

Abstract. An unphysical checkerboard pattern is identified in E3SMv2 and E3SM-MMF that detectable across a wide range of timescales, from instantaneous snapshots to multi-year averages. A detection method developed quantify characteristics the signal by cataloguing all possible configurations eight adjacent neighbors for each cell on model's cubed sphere grid using daily mean data. The only fou...
