1. A computer-implemented method of adjusting wellbore parameters, the computer-implemented method comprising:
receiving, from an image device, image data of a region of interest (“ROI”) from a mechanical mud separation machine (MMSM), the image data including image data of an object flow, wherein the ROI is determined by:
identifying a ledge of an MMSM within the image data, the ledge being a location where objects in an object flow begin to free fall;
setting a top edge of the ROI at the ledge; and
identifying a frames per second of an imaging device capturing the image data; and
calculating a vertical length of the first ROI based on the frames per second of the imaging device and the ledge;
identifying, using the image data of the ROI, at least one wellbore-state indicator;
determining, based on in part the identifying at least one wellbore-state indicator, to send information to control at least one wellbore parameter; and
sending the information, wherein sending the information causes a change to at least one wellbore parameter.
