Method to improve object recognition in high-resolution vision systems

A vision system, comprising:

• an image sensor configured to capture an image having a first resolution of a scene in which multiple objects are positioned, the image being at a first analysis level and each of the multiple objects are associated with an object class of a plurality of object classes;
• and
• at least one computing device in electrical communication with the image sensor, the at least one computing device configured to:
• generate, from the image, at least one additional image having respective lower resolutions, each of the at least one additional image being at at least one second analysis level;
• use a map that associates one or more of the object classes with one or more different analysis levels to indicate which of the one or more object classes to identify at the corresponding analysis levels;
• execute a multiclass classifier for each of the corresponding analysis levels to identify objects of the object classes within the respective images;
• form a list derived from the identified objects;
• and
• output the list.
