This keypoint detection step is a variation of one of the blob detection methods developed by Lindeberg by detecting scale-space extrema of the scale normalized Laplacian; that is, detecting points that are local extrema with respect to both space and scale, in the discrete case by comparisons with the nearest 26 neighbors in a discretized ....

The Smooth Laplacian modifier allows you to reduce noise on a mesh's surface with minimal changes to its shape. It can also exaggerate the shape using a negative Factor. The Smooth Laplacian is useful for objects that have been reconstructed from the real world and contain undesirable noise. It removes noise while still preserving desirable.

Laplacian pyramid blending with a mask in OpenCV-Python Raw lap_pyr.py This file contains bidirectional Unicode text that may be interpreted or compiled differently than what appears below. To review, open the file in an editor that reveals hidden Unicode characters. Learn more about bidirectional Unicode characters. Since the actual blending step is trivial (it's just standard alpha matting) the most important computations are (1) computation of the Laplacian pyramid of an image and (2) reconstruction of the Gaussian pyramid of an image given its Laplacian pyramid.

DESCRIPTION: LAPLACIAN generates an output image which is a user defined mix or blend of the original image and a Laplacian convolution filtered version of the image. This is achieved by forming a single convolution kernel whose weights depend upon a mixing of the Laplacian coefficients and the identity kernel.

  • Make all of your mistakes early in life. The more tough lessons early on, the fewer errors you make later.
  • Always make your living doing something you enjoy.
  • Be intellectually competitive. The key to research is to assimilate as much data as possible in order to be to the first to sense a major change.
  • Make good decisions even with incomplete information. You will never have all the information you need. What matters is what you do with the information you have.
  • Always trust your intuition, which resembles a hidden supercomputer in the mind. It can help you do the right thing at the right time if you give it a chance.
  • Don't make small investments. If you're going to put money at risk, make sure the reward is high enough to justify the time and effort you put into the investment decision.

A Laplacian pyramid is very similar to a Gaussian pyramid but it saves the difference between the blurred levels.
