1. Materials required for hardware First, you need a Raspberry Pi board. Here we use the Raspberry Pi Zero 2 W. At the heart of the Raspberry Pi Zero 2 W is the RP3A0, a custom system-in-package designed by Raspberry Pi UK. Powered by a quad-core 1-bit ARM Cortex-A512 processor clocked at 53GHz and 2MB […]

Orange Pi (orangePiZero2) 2: Driver development, writing code to control the level of the IO port
1. View the chip manual Go to the official website to download the chip manual and view the manual. 1. As can be seen from the chip manual, the base address of GPIO (0x0300B000): 2. You can see the PC offset (0x0048) from the chip manual: The address of GPIOx is the GPIO base address […]
Semantic-Guided Zero-Shot Learning for Low-Light ImageVideo Enhancement
Paper reading: Semantic-Guided Zero-Shot Learning for Low-Light Image/Video Enhancement Code: https://github.com/ShenZheng2000/SemantiGuided-Low-Light-Image-Enhancement One possible way to increase brightness in low-light conditions is to use a higher ISO or longer exposure time. However, these strategies exacerbate noise and introduce motion blur respectively [2]. Another reasonable approach is to use modern software such as Photoshop or Lightroom to […]
