Example image processing methods, apparatus, systems and articles of manufacture (e.g., computer readable media) to implement multi-object multi-view association are disclosed. Examples disclosed herein obtain initial two-dimensional (2D) bounding boxes of detected objects in multiple images of a scene from multiple cameras, generate a plurality of three-dimensional (3D) bounding boxes potentially corresponding to one or more objects to be tracked, and generate a weight that represents a strength of association between two detected objects respectively in two images of the multiple images. The weight is based on projection of one of the 3D bounding boxes back to at least one of the two images to generate a re-projection 2D bounding box.
