Installation

From GitHub:

pip install git+https://github.com/keyneoei/vidtracker.git

Or locally:

git clone https://github.com/keyneoei/vidtracker.git
cd vidtracker
pip install .

🖥 CLI Usage

python -m vidtracker.cli --input=data/input/cliffbar/imgs --output=data/output/cliffbar --tracker=DFS --show_frames

Usage Example (Python)

from vidtracker import DFSTracker, MILTracker, LKTracker

tracker_type = "DFS"    # or "MIL", "LK"
frame = ...             # read video frame
init_bbox = ...         # init bbox
cfg = ...               # configuration (box)

if tracker_type == "DFS":
    tracker = DFSTracker(frame, init_bbox, cfg)
elif tracker_type == "MIL":
    tracker = MILTracker(frame, init_bbox, cfg)
elif tracker_type == "LK":
    tracker = LKTracker(frame, init_bbox, cfg)

# Process subsequent frames
x, y, w, h, angle = tracker.process_frame(next_frame)
