A method of rasterising a line in computer graphics determines whether the line's start and/or end is inside a diamond test area within the pixel. If the end is not inside and the start is inside, the pixel is drawn as part of the line. If neither the start nor the end of the line are inside, it is determined whether the line crosses more than one extended diamond edge and if so, it is further determined (i) whether an extended line passing through the start and end is substantially vertical and touches the right point of the diamond area, (ii) if the extended line touches the bottom point of the diamond area, and (iii) whether the extended line is on a same side of each point of the diamond area. If any of (i), (ii) and (iii) is positive, the pixel is drawn as part of the line.

A computer implemented method comprising: receiving a report on a condition of a human or animal subject, composed by a user based on a scan of the subject; inputting the current report and the scan into a trained machine learning model; and based on the report and the scan, the machine learning model generating one or more suggestions for updating the text of the report. The method further comprises causing a user interface to display to the user one or more suggestions for updating the text of the report, with each respective suggestion visually linked in the user interface to a corresponding subregion within at least one image of the scan based upon which the respective suggestion was generated.

A software system and method are disclosed for characterizing multi-level Pulse Amplitude Modulation (PAMn) eye diagrams using integrated image processing, curve fitting, and statistical analysis. The system processes a photograph or digital file of a PAMn eye diagram, typically captured from a digital sampling oscilloscope, and converts it into a one unit interval (1UI) PAMn pattern. In this pattern, horizontal lanes and transition lane center curves are sampled and fitted to extract the mean and width of each lane. Two 1UI PAMn patterns are then combined to reconstruct a two unit interval (2UI) PAMn eye diagram with statistical features. The system calculates eye heights and eye widths for each eye based on the extracted lane statistics parameters and enables mask testing by aligning a predefined test mask with the center of each eye region to evaluate compliance.

The present disclosure provides an image processing method and apparatus, a device and a storage medium. The method comprises: first, determining a first contour point and a second contour point of a target object on an image to be processed, wherein the first contour point belongs to points on a first contour line of the target object, and the second contour point belongs to points on a second contour line of the target object; secondly, constructing, on the basis of the first contour point and the second contour point, a grid corresponding to the target object, and shifting the second contour point in the grid on the basis of a deformation parameter corresponding to the target object, to obtain a deformed grid; and then, generating, on the basis of the deformed grid, a deformed image corresponding to the target object. Hence, according to embodiments of the present disclosure, the grid of the target object on an image to be processed is deformed, such that the image processing function is realized, and the display effect of the target object on said image can be improved, thereby improving user experience.

Digital object fusion techniques and systems are described. In one or more examples, a base object and an adornment object are received and anchor points of the base object and the adornment object are detected by a digital object fusion system. The digital object fusion system then identifies linked anchor points from the anchor points as supporting a link between the base object and the adornment object. A path is fused by the digital object fusion system that defines the base object and the adornment object based at least in part on the linked anchor points. From this, a fused object is generated by the digital object fusion system by propagating visual style data to the path from the base object or the adornment object.
