opencv – resize, pyrUp and pyrDown image pyramid (Gaussian pyramid, Laplacian pyramid) and size scaling (upsampling, downsampling)…
We often convert images of a certain size into images of other sizes. If we need to enlarge or reduce the size of the image, we can use the following two methods in OpenCV: resize function, the most direct method. The pyrUp and pyrDown functions, two functions related to the image pyramid, perform upsampling and […]
Opencv image scaling (enlargement, reduction), flipping, rotating
Article directory Opencv image scaling (enlargement, reduction), flipping, rotating 1. Why interpolation is needed during image scaling and rotation: 2. Common interpolation algorithms include: 3. Image scaling, flipping, and rotating: (1) Image scaling cv2::resize(), a function used to change the size of an image. It can be used for image enlargement and reduction operations: Function […]
Winform form adaptive scaling according to the new form size
The following is Baidu’s method of finding out what others have done. You can test it: class AutoSizeFormClass { //(1). Declare the structure and only record the initial position and size of the form and its controls. public struct controlRect { public int Left; public int Top; public int Width; public int Height; } //(2).Declare […]
Problems and solutions that may be encountered when Qt adapts to different resolutions and scaling rates
Without special processing, Qt’s UI window may have display problems at different resolutions and scaling rates. Common ones include: Sub-controls are stacked and cannot be displayed completely The window size becomes larger and exceeds the display range of the screen The control is deformed and the aspect ratio is unreasonable Blurred interface The font size […]
OCCT7.6+QT5.14.2 realizes mouse dragging, scaling and rotation
After OCCT7.6 is installed, you will get the following folders The two gray folders were created by me , one is a project for occt, and the other is a DLL file of a third-party library. Add a QT project In the vs environment, the third child is the same: 1 Including directory: D:\OpenCASCADE-7.6.0-vc14-64\opencascade-7.6.0\inc 2 […]

Amazon Aurora MySQL and Amazon RDS for MySQL cluster failover and read-only instance scaling time testing
01 Testing background Amazon Aurora MySQL is a MySQL-compatible relational database built for the cloud with performance and availability comparable to commercial databases at 1/10 the cost. Amazon RDS for MySQL makes it easier to set up, operate, and scale MySQL deployments in the cloud. With Amazon RDS, you can deploy a scalable MySQL server […]
The Art of Database Scaling: Designing Scalable EventDr
Author: Zen and the Art of Computer Programming 1. Introduction With the rise of big data, cloud computing and other technologies, software architecture has also undergone tremendous changes. The main goal of software architecture design is to build a software system that operates well and is resilient. In order to achieve this goal, a series […]
