Abstract: In implementations of transferring vector style properties to a vector artwork, an artwork editing system directly processes artwork represented by vector graphics, unlike systems that process raster graphics. The artwork editing system transfers vector style properties from shapes of a style vector artwork to shapes of a content vector artwork based on overlapping shapes between the two artworks and in proportion to an amount of the overlap. A user may select vector style properties to transfer, such as fill content, stroke color, stroke width, stroke dashing, etc., and a percentage of the vector style property to transfer. Accordingly, a designer may transfer vector style properties of the designer's selection to a vector artwork efficiently and predictably, in real-time (e.g., without perceptible delay to the designer), without undesired distortions that are commonly introduced by neural networks, and without the cost associated with neural networks.

Abstract: The automated treatment of agricultural fields allows precise application of treatment to only areas of the field requiring treatment, allowing reduced use of agricultural products such as pesticides and the related reduction in environmental stress. Such automated treatment requires the monitoring of image information of the field to detect objects of interest such as weeds. Such monitoring of image information of the field suffers from the real world problem of shadows cast from the agricultural equipment and/or adjacent trees or structures that cast shadows across the field. Shadows are extracted from the image data by smoothing the data, and developing a shadow mask by employing an intensity histogram and identifying a local minima in the darker intensities of the histogram to identify a shadow threshold. The image areas within the shadow area detected by said mask are then corrected by multiplication with correction coefficients to extract the shadow.
