### Multi-Camera Tracking Objectives and Goals In the context of computer vision, multi-camera tracking aims to monitor and follow objects across multiple camera views seamlessly. The primary objective is to maintain consistent identification and localization of targets as they move through different fields of view provided by a networked system of cameras. The specific goals include ensuring accurate detection and recognition of individuals or entities within each frame captured from various angles and positions[^1]. This involves addressing challenges such as occlusion, varying lighting conditions, and changes in appearance due to perspective differences between cameras. Another critical goal is achieving real-time performance while maintaining high precision in tracking accuracy over time. Systems must be capable of processing large volumes of video streams efficiently without significant delays that could compromise operational effectiveness[^2]. To accomplish these tasks effectively, advanced algorithms integrate intelligence features like deep learning models trained specifically for object classification and re-identification across non-overlapping areas covered by separate devices forming part of an integrated surveillance setup. ```python import cv2 from mtcnn import MTCNN detector = MTCNN() def detect_faces(image_path): image = cv2.imread(image_path) result = detector.detect_faces(image) bounding_boxes = [] for face in result: bbox = face['box'] bounding_boxes.append(bbox) return bounding_boxes ```
