The tutorials of Huanfeng Gene not only teach you how to use it, but also regularly analyze some related articles. Learning the tutorials is only the basis, but integrating the analysis results into the articles is the purpose. I think our tutorials are pretty good, and you can follow our If you get good results […]

13.4 Object Detection Anchor Box Labeling & Non-Maximum Suppression
Anchor box shape calculation formula Suppose the height of the original image is H and the width is W Anchor box shape detailed formula derivation Anchor boxes of different shapes are generated with each pixel as the center # s is the zoom ratio, ratio is the aspect ratio def multibox_prior(data, sizes, ratios): “””Generate anchor […]
Hand tearing NMS (non-maximum suppression) IoU (intersection-over-union ratio) Python/C++
IoU concept IoU code Python code def iou(box1, box2): # Calculate the coordinates of the upper left and lower right corners of the overlapping area x1 = max(box1[0], box2[0]) y1 = max(box1[1], box2[1]) x2 = min(box1[2], box2[2]) y2 = min(box1[3], box2[3]) # Calculate the width and height of the overlapping area width = max(0, x2 […]

MATLAB Image Processing Realizes Highlight Suppression
Below are several processing examples of highlight suppression using MATLAB. 1. Bright light suppression method based on maximum value filter The principle is to subtract the pixel value from the maximum value in a neighborhood of a certain size around a pixel to achieve the effect of bright light suppression. In MATLAB, you can use […]

Python implements NMS non-maximum value suppression algorithm
Python implements NMS non-maximum value suppression algorithm I won’t go into details about the specific process of the NMS algorithm. There are many explanations of the algorithm on the Internet, and the code is directly listed below bbox_iou is the code used to calculate the IoU value between borders, which is the code in YoloV5 […]
OV5640, FPGA, Fast corner detection, non-maximum suppression, Ethernet real-time image transmission, Zynq, Linux, SDL video display

For Linux system transplantation under Zynq, please refer to: Zynq traditional way to transplant linux. If you find it troublesome, you can directly use […]
Learn how to convert NCM files to MP3–What important things should you do after charging the network and suppressing cloud members?
Not much to say, just because VIP’s songs are in ncm format, they cut my leeks hard! I’m using Wangyiyun to listen to music, and then I’ve charged up as a VIP. Don’t ask, it’s because I like listening to unpopular songs, otherwise I would have used QQ Music long ago, wouldn’t I? After searching […]
Suppress gradient exception initialization parameters (to prevent gradient disappearance and gradient explosion)
Here is a comparison of three parameter initializations, namely: full initialization to 0, random initialization, and abnormal gradient suppression initialization. The first is the function init_utils.py required for forward and backward propagation, drawing, and loading data: # -*- coding: utf-8 -*- import numpy as np import matplotlib.pyplot as plt import sklearn import sklearn.datasets def sigmoid(x): […]
