Foreword In actual AD acquisition scenarios, there will be effects of periodic changes and occasional pulse fluctuation interference on AD acquisition. Here a combination of median average filtering + recursive average filtering is used Refer to the code framework written by predecessors, and also refer to the blog below by blogger GuYH_, and make slight […]

02-Algorithm-master formula, median value, logarithmizer (C++ implementation)
2. Understand O(N*logN) sorting Section 1, master formula ? In programming, recursion is a very common algorithm. It is widely used because of the simplicity of the code. However, compared with sequential execution or loop programs, the time complexity of recursion is difficult to calculate, and the master formula is used to calculate the time […]

opencv-python–image enhancement (Gaussian filter, mean filter, median filter, histogram equalization, gamma transform)
Topic 1: Gaussian noise with a mean value of 0 and a variance of 0.03 is added to 20 noisy images. Please denoise and enhance the images and write down the principle. 1. Algorithm principle: Gaussian filtering is a linear smoothing filter, which is suitable for eliminating Gaussian noise and is widely used in the […]

Intel’s oneAPI implements 5*5 median filtering of bmp images
Intel’s oneAPI is a powerful software development toolset designed to support cross-platform parallel computing and heterogeneous computing. It provides a unified programming model that allows developers to efficiently program in parallel on a variety of hardware platforms, including CPUs, GPUs, and FPGAs. At the heart of oneAPI is Data Parallel C++ (DPC++), an extended programming […]
