use of previous_frame in motion_heatmap section ?

I uncommented the previous_frame at all the 3 instances & the code still worked . Can you describe me the use of deep-copying the converted gray frame ?

Incorrect output

Hi,
At first, I have tired gauge-2.jpg. But the reading is not right.
It shows the results 21.996410023136274. I passed the values

Min angle (lowest possible angle of dial) - in degrees: 50
Max angle (highest possible angle) - in degrees: 320
Min value: 0
Max value: 200

but the results should not be ~22. it's roundabout 30.

The second problem is I am using some different type of images and the results are far away. How I can improve this project to work on my custom inputs?
Here are the results on my inptus.

and for this kind of inputs, it is throwing errors.

gauge number: 6
Min angle (lowest possible angle of dial) - in degrees: 50
Max angle (highest possible angle) - in degrees: 310
Min value: 0
Max value: 0.6
Enter units: mps

how to display a video with heatmap?

hello,

this is not an issue, its a question.

How can you display a video with heatmap?
Or how can I make an video output, not image output?

Not working for gauge-2.jpg

Hi,
I executed code on gauge-1.jpg, and got results successfully. But If I run the same code for gauge-2.jpg which is in "images" folder, I am getting this error.

File "analog_gauge_reader.py", line 199, in get_current_value
   x1 = final_line_list[0][0]
IndexError: list index out of range

What I am missing ??

181: error: (-215:Assertion failed) !_src.empty() in function 'cv::cvtColor'

got this error before storing cv2.imwrite('diff-overlay.jpg', result_overlay). got above error at end of excution
