Hybrid Cascade Model for Face Detection in the Wild Based on Normalized Pixel Difference and a Deep Convolutional Neural Network
The main precondition for applications such as face recognition and face de-identification for privacy protection is efficient face detection in real scenes. In this paper, we propose a hybrid cascade model for face detection in the wild. The cascaded two-stage model is based on the fast normalized pixel difference (NPD) detector at the first stage, and a deep convolutional neural network (CNN)...
متن کاملAn Efficient Algorithm for Face Detection in Color Images
In this paper, we propose a novel approach for robust skin segmentation and face similarity measure. The proposed skin segmentation is a method for integrating the chrominance components of well-known color models. The goal of the method of skin detection is to select the appropriate color model for verifying the skin pixel under different lighting conditions and various types of skin color. Th...
متن کاملAdaptive Pixel Difference Classification, an Efficient and Cost Effective Algorithm for Motion Estimation
In this paper we present a simple adaptive block-matching algorithm for video compression. Our method is an adaptive approach to pixel difference classification (PDC) matching criterion. A constant threshold is used in original PDC algorithm in which optimum threshold varies from sequence to sequence. In contrast to the original PDC algorithm, adaptive PDC (APDC) employs a time variant threshol...
متن کاملComputationally Efficient Face Detection
This paper describes an algorithm for finding faces within an image. The basis of the algorithm is to run an observation window at all possible positions, scales and orientation within the image. A non-linear support vector machine is used to determine whether or not a face is contained within the observation window. The non-linear support vector machine operates by comparing the input patch to...
متن کاملEfficient V-BLAST Detection Using Modified Fano Algorithm
We propose a sub-optimal but computationally efficient Modified Fano Detection algorithm (MFD) for V-BLAST systems. This algorithm utilizes the QR decomposition of the channel matrix and the sequential detection scheme based on tree searching to find the optimal symbol sequence. For more reliable signal detection, the decoder is designed to move backward for the specified value at the end of th...
