The gray-level absolute central moment of the first order provides ridges at gray-level discontinuities as well as a conventional gradient of Gaussian (GoG). A mass center b of the gray-level variability can also be associated to the first absolute central moment. When given a starting point ...
You haven't helpped us a whole lot with your screen shots because we can't see enough of the layers panel, so I am going to have to guess. From what I can see, you have applied the Gaussian Blur to a layer filled with a solid colour. A blur will make no...
Gaussian process regression in scikit-learn provides a conditional mean and variance, (y_,\sigma_^2), based upon the observed data, (y,\sigma^2). But given (y_,\sigma_^2), how can you compute the variance of \frac{dy_}{dx_} in scikit-learn? The formula for doing this is given...

The 3D Gaussian splatting methods are getting popular. However, they work directly on the signal, leading to a dense representation of the signal. Even with some techniques such as pruning or distillation, the results are still dense. In this paper, we propose to model the gradient of the ...
GradientOrientationFilter is used to obtain the orientation of rapid-intensity change for applications such as texture and fingerprint analysis, as well as object detection and recognition.
This work presents a method of evaluating the intensity distribution of a Gaussian beam in a weakly inhomogeneous medium when it has been truncated by a circular aperture. An analytical expression for the diffracted field is obtained in terms of Bessel functions.doi:10.1080/09500349114551801...
Here,f(s;θ) is the output of the neural network, and the softmax function converts the output into a probability distribution over actions. Continuous Actions For environments with continuous action spaces, the policy is often represented as a Gaussian distribution. Picture adjusting the volume ...
Many models in machine learning are framed as maximum likelihood estimation (MLE) problems, where the goal is to adjust parameters to maximize the likelihood of the observed data. Examples include Gaussian Mixture Models, Hidden Markov Models, and some Neural Network configurations. Gradient ascent is...
