isp-tools's Introduction

ISP-tools

isp_background

​ 图像信号处理(Image Signal Process, ISP)芯片的仿真系统,实现了原始RAW数据到最终sRGB图像的渲染。

​ 现有的isp研究对科研人员不友好,一般实验室也没有芯片公司的软硬件环境。多阶段ISP的每个阶段通常含有基于传统和深度学习的多种算法,每个模块的中间结果无法获得;现有人员提出了基于深度学习的端到端ISP,一步渲染。ISP的不同模式、算法和组合都会影响图像质量,然而目前也缺乏一个统一评测平台。

​ 针对上述问题,我们用Python实现了ISP芯片的仿真系统,为使用开发ISP算法提供便利的实验环境。
