Abstract:
Disclosed are an apparatus and method for extracting a skin area to block a harmful image. The apparatus includes an image extraction unit, a skin sample area extraction unit, a background sample area extraction unit, a probability density function computation unit, and a skin area extraction unit. The image extraction unit extracts an image from image media. The skin sample area extraction unit extracts a skin sample area of the image based on prior information. The background sample area extraction unit extracts a background sample area of the image based on the prior information. The probability density function computation unit calculates the probability density functions of the skin sample area and the background sample area. The skin area extraction unit extracts a skin area from the image based on the probability density function of the skin sample area and the probability density function of the background sample area.
Abstract:
Disclosed herein are an apparatus and method for generating evidence video. The apparatus includes a video object indexing unit, a video object search unit, and an evidence video generation unit. The video object indexing unit recognizes an object by storing and analyzing videos received from multiple surveillance cameras, extracts the features of the recognized object, and then generates object metadata. The video object search unit compares received search conditions with the object metadata, and then outputs search results, including the feature information of at least one object, which corresponds to the search conditions. The evidence video generation unit generates an evidence video by aggregating only videos including a specific object selected from the search results.
