Query: Human Extraction and Scene Transition utilizing Mask R-CNN   Object detection is a trendy branch of computer vision, especially on human
recognition and pedestrian detection. Recognizing the complete body of a person
has always been a difficult problem. Over the years, researchers proposed
various methods, and recently, Mask R-CNN has made a breakthrough for instance
segmentation. Based on Faster R-CNN, Mask R-CNN has been able to generate a
segmentation mask for each instance. We propose an application to extracts
multiple persons from images and videos for pleasant life scenes to grouping
happy moments of people such as family or friends and a community for QOL
(Quality Of Life). We likewise propose a methodology to put extracted images of
persons into the new background. This enables a user to make a pleasant
collection of happy facial expressions and actions of his/her family and
friends in his/her life. Mask R-CNN detects all types of object masks from
images. Then our algorithm considers only the target person and extracts a
person only without obstacles, such as dogs in front of the person, and the
user also can select multiple persons as their expectations. Our algorithm is
effective for both an image and a video irrespective of the length of it. Our
algorithm does not add any overhead to Mask R-CNN, running at 5 fps. We show
examples of yoga-person in an image and a dancer in a dance-video frame. We
hope our simple and effective approach would serve as a baseline for replacing
the image background and help ease future research.
