Target detection notes - overview and common data sets

Overview and common data sets 0. General Have basic knowledge of classification network Target detection is divided into two categories: one stage and two stage 1.Two-Stage: Faster R-CNN 1) generate candidate boxes (rpns) through special modules, find prospects and adjust bounding boxes (based on anchors) 2) further classify and adjust the ...

Code implementation of calculating the similarity between tensor s according to Euclidean distance and cosine similarity

Generally, in the process of model reasoning on the end side, the quantized data is used to participate in the calculation of each layer, rather than the original float data type. The usual quantized data types include UINT8/INT8/INT16, etc. due to the difference of data representation range, the accuracy loss must be involved in the quantizati ...

Q-learning(DQN): the swing of reinforcement learning

1. Project introduction Q-learning: Q-learning was first proposed in 1989 and was initially based on tabular form. DQN: DQN (deep Q network) was proposed only in 2013. It is a Q-learning algorithm based on deep neural network, and it is also the most commonly used Q-learning algorithm at present. Objectives of the project: The DQN algorithm ...

Eye State Recognition in Deep Learning & Drawing of Confusion Matrix

This experiment is based on the CNN network built by ourselves to classify eye state. Originally, it was intended to migrate learning to classify using VGG16 network. However, the effect of the experiment is very poor and the speed is very slow. It should be the blogger's own problem. However, the model of CNN network built by ourselves is very ...

Introduction to OpenCV -- source code analysis of small face detection projects that can be used

0x00 overview of ideas The overall logic of the program is to recognize your face and save count (counter) pictures of your face, then exit, or press q while running. There are two important cycles 1. Call camera loop continuously ----- while true 2. Process the function of each face recognized by the recognition function ----- for xywh i ...

On VMD -- variational modal decomposition

In many scenarios, we need to decompose the signal to facilitate our next operation. The commonly used decomposition methods can include EMD family, such as EMD, EEMD, FEEMD, CEEMDAN, ICEEMDAN, etc. of course, there are also wavelet decomposition and empirical wavelet decomposition. In short, there are many decomposition methods. Different deco ...
