Basic image operation and processing [Chapter 1 of computer vision]
I PIL:Python image processing library
PIL(Python Imaging Library), which provides general image processing functions, has a large number of useful basic image operations, such as image scaling, clipping, rotation, color conversion and so on. The following will give specific examples of some PIL basic image operations.
1. Read an image and dis ...

Image data type conversion, image stretching and band judgment
Through the pit... I won't mention it. Before the training of in-depth learning, when the data sets are almost completed, that is, downloading, labeling, cutting and screening are all finished. Sent to the network for training. Due to the inconsistency of data types, the prediction ...

Full convolution network (FCN) practice: using FCN to realize semantic segmentation
Full convolution network (FCN) practice: using FCN to realize semantic segmentation
FCN classifies images at pixel level, which solves the problem of semantic segmentation. Unlike the classical CNN, which uses the full connection layer to obtain a fixed length feature vector for classification after the convolution layer (full connection layer ...

[Python + + opencv + Python] license plate extraction, segmentation and recognition
If you want to complete the project, I will put the github link at the end of the article: You can see that the final identification license plate number is min G99999.
In fact, I accidentally thought of doing a small project with c + + in the winter of the previous year, and then realized the license plate extraction and segmentation with c+ ...

Camera calibration for binocular vision
Binocular vision is based on geometric mathematics, and mathematical derivation is boring. Therefore, I will not introduce the mathematical principles here, but briefly describe the process of binocular vision.
Binocular vision mainly includes five parts: camera calibration, image distortion correction, camera correction, image ...

Intelligent route planning of MyCobot manipulator head
I've been struggling whether to talk about the head movement first or the spatial coordinate system first. Later, I decided to talk about the head movement first, so that we can first feel how the manipulator is positioned in space, and then we will introduce in detail the spatial coordinates of the manipulator in the next section. Spatial coor ...

UNet + + learning notes (backbone network + code)
paper
1 Abstract
The article puts forward that UNet mainly has the following two defects:
① the optimal depth of the network is unknown, which requires a large number of experiments and integration of networks with different depths, resulting in low efficiency;
② skip connection introduces unnecessary restrictions, that is, it restricts fea ...

Project background
I recently found that there was no good example when I read the resnet50+FPN version of Faster-RCNN when I was preloading and loading data, when I read the class loaded by paddlepaddle's official data.
So I did this today, how to make a d ...
