Shot Detection

Easy-to-use

python shotdetect.py # to process a single video
python shotdetect_p.py # to process a list of videos in parallel

Introduction

Shot detection from videos with useful portals for long complicated videos, e.g., movies scenarios. The repo is based on PySceneDetect, which is under BSD 3-Clause License.

Features

• Parallel processing.
• Keyframe saving.
• Optimal detector that is tested on movie/tv epsoides scenarios, e.g., HSV-LUV joint model.
• Average sampler.

Misc

The following function could help you to organize the output list file (in the case with three keyframes) into a dictionary.

def read_shot_list(txt_fn):
    list_raw = read_txt_list(txt_fn)
    shot_dict = {}
    for shot_ind, item in enumerate(list_raw):
        shot_dict[str(shot_ind).zfill(4)] = {
            "start": int(item.split(" ")[0]),
            "end": int(item.split(" ")[1]),
            'keyf': int(item.split(" ")[3])
            }
    return shot_dict
