  How to realize Image Fourier transform with Python OpenCV

  This article is about how Python OpenCV implements the Fourier transform of images. The editor thinks it is very practical, so share it with you as a reference and follow the editor to have a look. Two-dimensional discrete Fourier transform (DFT) is usually used in two-dimensional image processing.

  Fourier, the father of signal analysis, obtained the Fourier transform in the study of thermodynamics, which changed the world

  Newton's "principles" opened the door to the study of natural mathematics, and colleagues in continental Europe extended Newton's ideas about the laws of nature to most fields of physical science. After the wave equation (the wave equation vibrating from the violin has become one of the basic theories supporting modern science and technology), many more have emerged one after another.

  Fourier and Monge, one of the most important mathematicians in France, made a large part of human civilization.

  Mongolia invented descriptive geometry (not to be confused with projective geometry); Fourier's classical study of the theory of heat conduction opened up the modern stage of mathematical physics. Without Monge's geometry, mass production of machines in the 19th century might not have been possible. Descriptive geometry is the key to make mechanical engineering a reality.

  Heisenberg uncertainty principle is a purely mathematical phenomenon.

  The original title: "Why is the principle of uncertainty uncertain?" I often hear people say that it is because the momentum of photons is affected by the interaction between photons and electrons, which leads to the Heisenberg uncertainty principle. The observer must influence the momentum of the electron

  Breakthrough innovation! Micro-Beauty Hologram (NASDAQ:WIMI) scaling projection Technology promotes augmented reality and Virtual reality to enter a New era

  Holography began to develop as early as the middle of the 20th century. At first, people mainly focused on how to use holography to achieve the reality of 3D images, in order to achieve a more immersive visual experience. However, the traditional holography is limited by its complex system design, computational complexity and space requirements.

  In the 19th century, the glory of mathematics and the "decline" of God, only Cauchy could compete with Gauss.

  The world of mathematics in the 19th century was an auspicious scene. ∶ Lagrange was still active in mathematics. Laplace was at the peak of his intelligence. Fourier devoted himself to studying his 1807 manuscript, which was later incorporated into his classic Hot Theory (1822); Gauss (Gau)
