Snakes can be periodic (for segmentation) or have fixed and/or free ends. The output snake has the same length as the input boundary. As the number of points is constant, make sure that the initial snake has enough points to capture the details of the final contour. Parameters: image(M, N) or (M, N, 3) ndarray.

Supports single and multichannel 2D images. Snakes can be periodic (for segmentation) or have fixed and/or free ends. The output snake has the same length as the input boundary. As the number of points is constant, make sure that the initial snake has enough points to capture the details of the final contour.
Feb 20, 2016 · There are problems with one input and one output that require millions of hidden units, and problems with a million inputs and a million outputs that require only one hidden unit, or none at all. Some books and articles offer "rules of thumb" for choosing a topopology -- Ninputs plus Noutputs dividied by two, maybe with a square root in there somewhere -- but such rules are total garbage .
By default, the padding is 0 and the stride is 1. In practice, we rarely use inhomogeneous strides or padding, i.e., we usually have p h = p w and s h = s w. 6.3.3. Summary. Padding can increase the height and width of the output. This is often used to give the output the same height and width as the input.
It is unclear how to model such inputs with a weight matrix of fixed size. Convolution is straightforward to apply; the kernel is simply applied a different number of times depending on the size of the input, and the output of the convolution operation scales accordingly. Taken from page 354, 9.7 Data Types, 3rd paragraph.
This converts the image to black and white, highlighting the objects-of-interest to make things easy for the contour-detection algorithm. Thresholding turns the border of the object in the image completely white, with all pixels having the same intensity. The algorithm can now detect the borders of the objects from these white pixels.

The Query is what determines the output sequence length, therefore we obtain a sequence of the correct length (i.e. target sequence length). In order to understand how the attention block works maybe this analogy helps: think of the attention block as a Python dictionary, e.g. In the code above, result should have value [1, 2].
