ExperimentSegViT: Semantic Segmentation with Plain Vision Transformers
I want to learn from the official SegViT model source code and deploy it to my local code file 1. Environment configuration The official website requires the installation of mmcv-full=1.4.4 and mmsegmentation=0.24.0 Before this, remember to uninstall the original version of mmcv and mmsegmentation pip uninstall mmcv pip uninstall mmcv-full pip uninstall mmsegmentation Install mmcv […]
Superpixel segmentation (SLIC algorithm), save the superpixel block obtained by segmentation
SLIC superpixel segmentation and save the segmented superpixel blocks: # https://github.com/LarkMi/SLIC/blob/main/SLIC.py import skimage from skimage.segmentation import slic,mark_boundaries from skimage import io import matplotlib.pyplot as plt from PIL import Image, ImageEnhance import numpy as np import cv2 # # np.set_printoptions(threshold=np.inf) path = ‘C:\Users\Administrator\Desktop\SLIC\’ img_name = ‘test.png’ img = io.imread(path + img_name,as_gray=True) #as_gray is grayscale reading, and […]
4. Thoughts on hashmap unsafe ConcurrentHashMap thread-safe use of segment lock mechanism
Thoughts on hashmap unsafe ConcurrentHashMap thread-safe use of segment lock mechanism Step 1: We used ConcurrentHashMap when logging in as a user and found that it is thread-safe. What is the mechanism to achieve thread safety? What is the principle of segment lock? Question: private Map allUserMap = new ConcurrentHashMap(); Tell me about this Answer:In […]
7. The underlying principle of LongAdder in the Atomic series (segmented locks improve concurrency performance)
The underlying principle of LongAdder of the Atomic series (segment lock improves concurrency performance) In this chapter, we will explain another problem brought by CAS. When the concurrency is intense, a large number of spins and CPU consumption will be generated, and how to use the segmented lock mechanism To solve this problem, we will […]

[Image segmentation] Satellite remote sensing image road segmentation: D-LinkNet algorithm interpretation
Foreword Because part of the content in the final project involves road segmentation of satellite remote sensing images, I did some research on related algorithms. The data set used in this article is DeepGlobe, which comes from a challenge in CVPR2018: DeepGlobe Road Extraction Challenge. D-LinkNet is the champion algorithm of this challenge. Considering that […]
