  2. Watershed delineation - Wikipedia

    en.wikipedia.org/wiki/Watershed_delineation

    Watershed delineation is the process of identifying the boundary of a watershed, also referred to as a catchment, drainage basin, or river basin. It is an important step in many areas of environmental science, engineering, and management, for example to study flooding, aquatic habitat, or water pollution.

  3. Watershed (image processing) - Wikipedia

    en.wikipedia.org/wiki/Watershed_(image_processing)

    A function W is a watershed of a function F if and only if W ≤ F and W preserves the contrast between the regional minima of F; where the contrast between two regional minima M 1 and M 2 is defined as the minimal altitude to which one must climb in order to go from M 1 to M 2. [7] An efficient algorithm is detailed in the paper. [8] Watershed ...

  4. Image segmentation - Wikipedia

    en.wikipedia.org/wiki/Image_segmentation

    The encoder structure follows the traditional stack of convolutional and max pooling layers to increase the receptive field as it goes through the layers. It is used to capture the context in the image. The decoder structure utilizes transposed convolution layers for upsampling so that the end dimensions are close to that of the input image.

    Version 9.2 introduced the use of XMDF (eXtensible Model Data Format), which is a compatible extension of HDF5. XMDF files are smaller and allow faster access times than ASCII files. The Watershed Modeling System (WMS) is a proprietary water modeling software application used to develop watershed computer simulations.
