Crop the image to reduce noise during OCR.

[ishanExtreme]

Overview

Image taken from camera installed on smart ICU captures other nearby things as well with the monitors, for example in below image there is a green board captured which makes it harder to categorize the data. Even in the monitor there is a table present which we dont require but will be read by OCR making data categorizing even harder.

What need to be done?

Crop the image so that only relevant data is left. Below shows the example of cropped image.

Current Solution

As in care_script.ipynb we are currently taking time as reference since we know the time at which image is taken from its metadata or system current time+-5 minutes we can get the bounding box of time and can extract crop image using that coordinates as a reference. But this approach is prone to errors if time of monitors is not synced or if time is not clearly visible.
