Android sensor data real-time display waveform through matlab

When we debugged VR Sensor on our platform in the past two years, we made an auxiliary tool and made a record here. At that time, some customers would report that there was an abnormal problem with the sensor in some VR apps, but there was no similar problem when replacing other VR apps. How to confirm if there is a p ...

Realization of histogram equalization in java

In the experiment of digital image processing, most of my classmates use MATLAB, because there are few codes about java implementation found on the Internet, but I prefer java implementation. However, they still refer to the code on the Internet, but they didn't say how to use buffer image. I chewed the ...
