Egocentric Video Summarization Based on People Interaction Using Deep Learning

الملخص EN

The availability of wearable cameras in the consumer market has motivated the users to record their daily life activities and post them on the social media.

This exponential growth of egocentric videos demand to develop automated techniques to effectively summarizes the first-person video data.

Egocentric videos are commonly used to record lifelogs these days due to the availability of low cost wearable cameras.

However, egocentric videos are challenging to process due to the fact that placement of camera results in a video which presents great deal of variation in object appearance, illumination conditions, and movement.

This paper presents an egocentric video summarization framework based on detecting important people in the video.

The proposed method generates a compact summary of egocentric videos that contains information of the people whom the camera wearer interacts with.

Our proposed approach focuses on identifying the interaction of camera wearer with important people.

We have used AlexNet convolutional neural network to filter the key-frames (frames where camera wearer interacts closely with the people).

We used five convolutional layers and two completely connected hidden layers and an output layer.

Dropout regularization method is used to reduce the overfitting problem in completely connected layers.

Performance of the proposed method is evaluated on UT Ego standard dataset.

Experimental results signify the effectiveness of the proposed method in terms of summarizing the egocentric videos.
