Thesource_infostructure is registered usingobs_register_source. OBS will use the structure to create the internal data and settings when the filter is added to an existing video source. A filter has its own independent set of properties and data settings, i.e. an instance of such settings ex...
In [16], we proposed an algorithm called data hiding smart pair toggling (DHSPT) which improves on DHPT by choosing the pair-toggling partner in a smart way to reduce visual artifacts. In this paper, we propose two methods called intensity selection (IS) and connection selection (CS) that...
This article is meant to be illustrative, not a one-to-one replica of the printing process. I’m embracing the artifacts that happen as a result of trying to imitate it. The images generated here may appear differently based on the device you’re using. Generating Halftones Traditionally, ha...
摘要: A frequency-modulation halftone screen and method for making same, utilizing local randomization (344) of a deterministic screen (342). The deterministic screen optimizes uniformity of the halftone dot distribution, while the local randomization suppresses artifacts due to subject moiré....
Test images were generated and the prints were visually examined for texture artifacts. A preferred viewing distance parameters value of 10-20 inches was indicated. The effect of the dither matrix size and the form of the visual cost function will be reported sometime in future. 展开 ...
Advantageously, this novel halftoning approach allows bad patterns, such as those that produce visual artifacts and/or undesirable textures or are otherwise visually displeasing, to be avoided in basic cell pattern growth.. In another aspect, this novel halftoning approach advantageously allows for, ...
15. The method of claim 2 wherein an indeterminate current pixel is in accordance with said criteria not assignable to an image type and is processed as an indeterminate pixel, and rendering said indeterminate pixel using a reproduction process that provides an image with minimal moire artifacts....
Reduction of artifacts in halftone screensA dot cluster halftone screen is modified to reduce harmonic artifacts by modelling artifacts from the screen in a frequency domain (210) and modifying threshold values in the screen to reduce amplitude of at least some of the modelled artifacts (212)....
As a result of such constraints, the resultingpreviews either work only under limited conditions or fail to predict some artifacts while erroneously predicting others that do not materialize in print. The approach presented here takes advantage of the flexibility of the HANS framework and the ...
