Bros! Don’t forget this when using focus and blur events!
Foreword Welcome to follow the public account of the same name “Panda’s Cat“. Articles will be updated simultaneously, and you can also quickly join the front-end communication group! Recently, my friends have encountered another need, which is to add a border style to the check box when it is selected, which is roughly as follows: […]
Fine-tune TrOCR and train TrOCR to recognize curved and blurred text
Click “AI Park” above, follow the public account, and choose to “star” or “pin” Author: Sovit Rath Compiled by: ronghuaiyang Introduction This article fine-tunes the TrOCR model on curved and blurred text datasets, and analyzes the code and training results at each step. The TrOCR (Transformer based Optical Character Recognition) model is one of the […]
Canvas – the principle of implementing animation, zooming in and blurring, and processing pictures
Canvas – the principle of realizing animation, zooming in and blurring, and processing pictures requestAnimationFrame implements animation It is the key to realizing animation in canvas. Different from setTimeout and setInterval, it does not need to set the time interval. The monitor is 60hz. Redraw 60 times per second. Therefore, the optimal interval for the […]
[Unity] URP screen post-processing UI blur effect implementation
Here Canvas(1) is set to Overlay to render The specified UI is high-definition and other UIs are blurry. However, this is very bad. If you open the UI and turn off the blur effect at this time, you need to restore these pinned UIs to the original Canvas, which means you need to manage 2 […]
[High Performance Computing] Opencl syntax and related concepts (4): Combined with opencv for image Gaussian blur processing
Directory Introduction to Gaussian Blur Main function: host side Device-side function: mywork.cl Comparison of renderings Introduction to Gaussian Blur Gaussian blur is a commonly used image processing technique used to reduce noise and details in images and achieve image smoothing. It is a convolution operation based on the Gaussian function, which achieves the blur effect […]
