Cut on vertical projection
First of all, I choose the license plate number as the projection image, which can be used as the license plate cutting technology.
Principle: after the license plate is processed, all the pixel values are stored in an array, and then the pixel values of each column are traversed and accumul ...

For the principle of svm In the previous chapter, we have a basic understanding, which is mainly realized by the relevant algorithm provided by OPencv. To fully understand the needs of SVM, we need to continue to spend time and energy. Here's how to use SVM classifier for object recognition. This time, take identifying basketball as an example ...

Histogram is a set of statistics of data, and the statistical results are distributed in a series of predefined bins.
The data here refers not only to the gray value, but also to any feature that can effectively describe the image.
Let's take an example. Suppose a matrix contains the information of an image (gray value ...

In this paper, the previous several articles are summarized to realize a small image retrieval application.
A small image retrieval application can be divided into two parts:
train to build the feature database of image set.
Retrieve, retrieve, given image, return the most similar image from the image library
The process of building imag ...

Python plays all kinds of multimedia, video, audio to pictures
We often encounter some operations to modify multimedia files, such as video editing, subtitle editing, audio separation, video audio mixed streaming, etc. Another example is the operation of audio files: audio clip, audio format conversion. Another example is our most commonly u ...

This section describes how to save and reload the spinner model (BERT, GPT, GPT-2, and Transformer-XL). You need to save three file types to reload the fine tuned model:
The model itself should be a model saved by PyTorch serialization( https://pytorch.org/docs/stable/notes/serialization.html#best-p ...

1, Mask operation
The mask operation of matrix is very simple. The idea is to recalculate the value of each pixel in the image according to the mask matrix (also known as the core). The value in the mask matrix indicates how much the value of the neighboring pixel (including the value of the pixel i ...
