Can white noise be correlated to a random signal
Can white noise be correlated to a random singal
Something can be correlated to something else but still be white. For example, let $X(t)$ be a white noise process, and let $Y(t) = 2X(t)$, then ...

Modelling MEMS accelerometer noise
Yes, you can use the datasheet noise density. Model the accelerometer as a source of white noise, and compute its characteristics.
That works to the extent that you can trust the data sheet.
That's ...

Modelling MEMS accelerometer noise
If your main focus is the end result (simulating the behaviour of an IMU, rather than learning to model the INS response from first principles) I'd recommend you cosnider gnss-ins-sim which will ...

How to detect faint, dense grains on an image?
You want to segment the image into "grain" and "non-grain" areas.
Then you want to label the "grain" areas.
Segmentation is easy in principle: you process the image into ...

Proper audio noise and artifact detection approach
That's a tough problem to solve. There are commercial solutions for this type of measurements (e.g. Audio Precision (ap.com), Listen, Inc. (https://www.listeninc.com/). They do an ok job but tend to ...
