Saving the frames processed by the Vehicle Type Recognition module

Saving the frames processed by the Vehicle type recognition module may be necessary for training the neural network or for debugging the module (see UrlServer debug window).

To enable saving the frames processed by the Vehicle Type Recognition module (UrlServer), namely a cropped frame that shows only a vehicle, it is necessary to specify the path to the folder in which these frames will be saved in the SavePictures registry key.

If the frame is not cropped correctly (the vehicle is cropped or there are foreign objects present in the frame), it is necessary to empirically determine the right cropping parameters as follows:

1. For the DeferLeft registry key, specify the coefficient by which the number plate width will be multiplied. The photo will be cropped from the left relative to the number plate at a distance equal to the product (DeferLeft * w).
2. For the DeferRight registry key, specify the coefficient by which the number plate width will be multiplied. The photo will be cropped from the right of the number plate at a distance equal to the product (DeferRight * w).
3. For the DeferUp registry key, specify the coefficient by which the number plate height will be multiplied. The photo will be cropped from the top relative to the number plate at a distance equal to the product (DeferUp * h).
4. For the DeferDown registry key, specify the coefficient by which the number plate height will be multiplied. The photo will be cropped from the bottom relative to the number plate at a distance equal to the product (DeferDown * h).
