## Matplotlib气象色标模块的构造与使用

介绍一个简单的Python 模块的开发过程。该模块使用csv表格制作兼容Python matplotlib库的气象、海洋绘图色标。
其后，分享了一些 git 的日常使用，以及使用conda-pack 进行conda环境打包、迁移的基本流程及注意事项。

This post shows an *approximation method to compute the IoU between oriented 2D boxes*.

This post shares a small tip for those who would like to download videos from websites like *Youtube* on their *IOS devices*, using a Linux shell emulator *ish*.

This post goes through the derivation of *signed distance function
(SDF)* with respect to oriented boxes in 2D.
I also showed *Python implementations* with some examples.

I implemented in Python an algorithm that fits the distribution of the sum of independent Gamma random variables.

This post talks about the binomial distribution with dependent trials, and Python implementation of the algorithm.

This post writes the training code of YOLOv3 and carries out some test training sessions on COCO 2014 dataset.

In this post we create a Dataset and a DataLoader class to load the COCO 2014 detection data.

In this post we create 3 essential tools in the object detection task: IoU (Intersection-over-Union), NMS (Non-Maximum suppression) and mAP (mean Average Precision).

In this post we load pre-trained weights for the YOLOv3 model and run some test inferences.
