Android Oximeter using Image Processing and IIR filter

Android Oximeter using Image Processing and IIR filter

Here in this blog, we’re going to create an Oximeter using Image Processing and IIR (Infinite Impulse Response) filter, camera API, and Surface View with Power manager.

IIR filter

IIR filters are one of two primary types of digital filters used in Digital Signal Processing (DSP) applications. They have been widely deployed in audio equalization, biomedical sensor signal processing, IoT/IIoT smart sensors, and high-speed telecommunication/RF applications.

Here users can easily check their Oxygen level by putting their finger over the camera and flashlight surface. Then by using the image processing and IIR filter this app will calculate the Oxygen level.
