Description

Background Art

[0001] Machine vision (MV) can refer to technologies used to provide imaging-based automated inspection and / or analysis for industrial applications (e.g., automated inspection, process control, and / or robotic guidance). Machine vision can include capabilities in industrial automation environments, but can also include capabilities in other environments, such as security and vehicle guidance. The entire machine vision process can include planning the details of the project requirements and then generating a solution. During operation, the machine vision process can start with the imaging process, followed by automated analysis of the image, and then extracting the required information from the automated analysis.

[0002] However, in some cases, the imaging process may not provide an image that can be used to extract information from the image. For example, an image of a medical device (e.g., a syringe or other container) may include a background that does not allow for accurate detection of specific aspects of the medical device from the image.
