Abstract: Some examples include systems and methods for monitoring emission indications. A system has an image sensor to capture an image of a flare stack. A computer vision engine is configured to determine whether an emission indicator captured by the image indicates an emission event. A server engine is configured to transmit a notification indicating whether the emission indicator indicates the emission event to a control system of the flare stack. The computer vision engine is configured to update one or more model settings, one or more thresholds, or a combination thereof based on one or more settings. In one embodiment, the computer vision engine is configured to identify, using a deep convolutional neural network (DCNN) model, the emission indicator captured by the image.
