Digital image processingparallel computingCUDAIJCSIThis paper presents an approach the point to point processing of digital images using parallel computing, particularly for grayscale, brightening, darkening, thresholding and contrast change. The point to point technique applies a transformation to each ...
The simplest image enhancement method is to use a 1 x 1 neighborhood size. It is a point operation. In this case, the output pixel (‘s’) only depends on the input pixel (‘r’), and the point operation function can be simplified as follows: s = T(r) Where T is the point oper...
A point light source, such as a laser, directs light onto film coated with a processing solution. Light from the film is measured to produce sensor data that corresponds to the colors in the film. The sensor data is used to construct a digital image corresponding to an image recorded on ...

An isolated point detection portion detects an isolated point in image data input from an image data adjustment portion. An isolated point removal portion makes a replacement of image data at a point
Point Cloud Analysis involves processing and classifying 3D point cloud data to extract meaningful information for various applications such as earth sciences, engineering, and autonomous driving. It plays a crucial role in reconstructing real-world environments in three dimensions and enabling scientific ...
In this case, an initial classification and/or semantic segmentation processing step is required. We use a classified ALS point cloud whose points are labelled according to their object class (building, ground, and unclassified). To group points belonging to one building, points are clustered by ...
