Introducing Simatest
A short introduction to Simatest, the camera and image signal processing (ISP) simulator in Imatest. Simatest starts from a raw or simulated image, applies simulated blur (MTF) and sensor noise, and runs it through an ISP pipeline built from blocks such as demosaicing, white balance, color correction, gamma, tone mapping, noise filtering and sharpening, in any order. The result can be analyzed with the same Imatest modules used on real cameras.
The video shows how Simatest lets you model complex ISP pipelines and measure the key image quality metrics they produce, with an example that compares measured and simulated noise and Edge/MTF results for a Panasonic Lumix LX5.
Simatest is part of Imatest 25.1 and later.
