Webb10 apr. 2024 · Because the input of the ViT encoder is a sequence different from the size of the image feature map, image serialization is a necessary step by dividing the extracted CNN feature map of size C × H × W into n square patches (p, p, c) in raster order (left to right, top to bottom), where p is a predefined parameter indicating the size of the patches. WebbFeatures and surfaces in ArcGIS can be represented as either discrete or continuous data. Discrete data, also known as categorical or discontinuous data, mainly represents objects in both the feature and raster data storage systems. A discrete object has known and definable boundaries. It is easy to define precisely where the object begins and ...
