In this paper, we design and evaluate a convolutional autoencoder that perturbs an input face image to impart privacy to a subject. Specifically, the proposed autoencoder transforms an input face image such that the transformed image can be successfully used for face recognition but not for gender classification. In order to train this autoencoder, we propose a novel training scheme, referred t...

To address one of the important and challenging problems – large-scale contentbased face image retrieval. Given a query face image, content-based face image retrieval tries to find similar face images from a large image database.Large-scale content-based face image retrieval is an enabling technology for many emerging applications. In this method, to utilize automatically detected human attribu...

In recent years, with the extensive application of video surveillance system in police’s criminal investigation, video investigation technology is playing a more and more important role in detection of cases. Key characters in case spots, such as criminal suspects and witnesses are often targets that attract most attentions. Therefore, face image become the key clue of a case. While in actual s...

Face image retrieval is an important issue in the practical applications such as mug shot searching and surveillance systems. However, it is still a challenging problem because face images are fairly similar due to the same geometrical configuration of facial features. In this paper, we present a face image retrieval method which is robust to the variations of face image condition and with high...

This paper presents a novel face detection algorithm. Face Detection is the process of locating faces in the image. Our aim is to locate all faces in the image irrespective of various challenges usually faced by researchers. Image including faces is the further key to intelligent vision-based human computer interaction & research attempts in face processing including face recognition, face moti...

Automatic content-based analysis and indexing of broadcast news recordings or digitized news archives is becoming an important tool in the framework of many multimedia interactive services such as news summarization, browsing, retrieval and news-on-demand (NoD) applications. Existing approaches have achieved high performance in such applications but heavily rely on textual cues such as closed c...

We present a novel method to relight video sequences given known surface shape and illumination. The method preserves fine visual details. It requires single view video frames, approximate 3D shape and standard studio illumination only, making it applicable in studio production. The technique is demonstrated for relighting video sequences of faces.

In this paper we present a method of automatic color correction of face images and its application in a face detection algorithm. The color correction method is based on the phenomenon of color constancy observed in human visual perception. This technique is further applied in a face detection system, which draws upon the analogy to the parallel organization of visual neural pathways, the magno...
