OpenCV Block-wise quantization - Google Summer Of Code 2024

My name is Daniele Affinita, and this report documents the work I completed during the Google Summer of Code 2024 for OpenCV, under the mentorship of Yuantao Feng.

TL;DR

Integrated Blockwise Quantization into OpenCV's DNN module, focusing on compressing model size for deployment on memory-constrained devices. Developed a tool to quantize models blockwise, achieving a 2-4x reduction in model size. Evaluated the performance, showing that blockwise quantized models retain accuracy closer to the original compared to standard int8 quantization.

Project Summary

Make Ubuntu packages 90% faster by rebuilding them

TL;DR

You can take the same source code package that Ubuntu uses to build jq, compile it again, and realize 90% better performance.

Setting

I use jq for processing GeoJSON files and other open data offered in JSON format. Today I am working with a 500MB GeoJSON file that contains the Alameda County Assessor's parcel map. I want to run a query that prints the city for every parcel worth more than a threshold amount. The program is

Examples are with //i.ytimg.com server just because it’s shorter, no other particular reason. You can use both.

张小龙离开家出差了一段时间，回家的时候发现家门口特别热闹，但走近一看大家却都哭丧着脸。张小龙觉得很奇怪，排开人群想进到家里去看看到底发生了什么，却被哥哥拦了下来。
