Recently, I am working on the object pose recognition program, and I have read many related papers. However, it can't be mastered just by looking at it. It is found that there is implementation of linemod in opencv. I'm going to look at this method first. I'll talk about the specific implementation process in the future and see ...

Summary: This paper mainly introduces an abstract process and scheme for row and column resolution of order class picture recognition results to help improve development efficiency. 1. Background In the face of order data paper files or pictures, only eye recognition is inefficient. Machine learning is needed to identify and analyze pictures to ...

Reprint:https://blog.csdn.net/qq_18649781/article/details/86484827 Introduction: There is a well-known conclusion in the field of image processing: if the Laplacian part is subtracted from the image, the edge of the image will be enlarged, so the image will become sharper. Based on the Laplac ...

In this paper, we will learn the basic knowledge of multi view geometry, such as pole, polar line and contrapolar constraint. When we use a pinhole camera to take photos, we will lose a lot of important information, such as the depth information of objects. Or how far each point in the image is from ...

Color space conversion of a picture Gray color space Single channel, value range [0255] 0 black 255 white RGB color space (BGR is used in opencv) The range of R, G and B channels in opencv is [0255].   HSV/HSL color space      H: 0-180  S: 0-255 V: 0-255 HSV is a representation of points in RGB color space in an inverted cone ...

1. Download the opencv3.2.0 installation package and go to the official website: http://opencv.org/releases.html , select the source of version 3.2.0, and download opencv-3.2.0.zip. 2. Install some libraries required by opencv, and try to install them as much as possible: sudo apt-get install build ...

The essence of mask: The image of the original image and the mask mask are processed and transported, and the result image is obtained. What is the operation of maps and masks? In fact, each pixel in the image and each corresponding pixel in the mask are processed and operated. For example: 1 & 1 = 1; 1 & 0 = 0; For example, a 3* ...
