Abstract:

This study tackles the challenge of splitting and merging in parametric active contours or snakes. The proposed method comprises three stages: (1) fully 4-connected interpolation, (2) snake splitting, and (3) snakes merging. For this purpose, first, the coordinates of snake points are separated into two corrupted 1D signals, with missing X/Y samples in the signals representing missing snakes’ coordinates. These missing X/Y samples are estimated using a constrained Tikhonov regularisation model, ensuring fully 4-connected snakes. Next, crossing points are identified by plotting snake points ont

Abstract:

The traditional method of using a conventional line-printer to produce rough isolines using raster contouring techniques in indigent environments is reviewed. It is suggested that methods where the isolines are boundaries between different symbols and having no thickness are better, and that numeric (hexadecimal) characters are best used to represent different levels of the dependent variable, especially where the slope of the surface is high. A comprehensive solution is also found to the usual problem with line‑printer maps of distortion due to unequal scales in the two axes of the coordinate

Abstract:

Geographical Information System (GIS) modelling using vector data is a commonly used method of modelling offering simple data input and analysis. However, the vector-data model assumes homogeneity in mapping units based on subjectively applied classification and simplification, and this may lead to over-simplification and consequent reduction in the variety of information obtained and uncertainty in results. This research aimed at refining the suitability modelling for sea cucumber (Holothuria scabra) using fully raster-based data for the waters of Kiowa Bay, Kahyapu village in the district of

Abstract:

Traditional 3D-Bresenham’s algorithm is efficient in generating lines on raster systems using only integer calculations. This algorithm is needed as a solution of hidden surface problem using depth-buffer method to calculate z value for each pixel, while calculated values of x and y are used to address frame buffer memory, z value is used to test hidden surface by saving the closest depth in depth buffer. In this paper Bresenham’s algorithm for plotting 3D-lines is examined then modified to simplify hardware requirements during implementation phase. Basing on efficiency of the algorithm on the

Abstract. Locating landslide-prone slopes is important, as landslides often threaten life or property where they occur. There is an abundance of statistical methods in the literature for estimating susceptibility to landslides, i.e., the likelihood of landslide occurrence based on the analyzed conditions. Still, there is a lack of readily available GIS tools for landslide susceptibility analysis, making it hard to reproduce or compare the results of different susceptibility assessments. The FRMOD is a Python-based tool for conducting landslide susceptibility analysis with the frequency ratio m

Abstract Most modern solar observatories deliver data products formatted as 3D spatio-temporal data cubes, that contain additional, higher dimensions with spectral and/or polarimetric information.

We developed the COlor COllapsed PLOTting (COCOPLOT) software as a quick-look and context image software, to convey spectral profile or time evolution from all the spatial pixels (x, y) in a 3D [nx, ny, nλ] or [nx, ny, nt] data cube as a single image, using colour.
