Multiresolution Methods in Face Recognition

چکیده
Wavelets have been a prominent image analysis tool over the past decade. Face recognition researchers use it for varied reasons – pre-processing, compression and feature extraction. We refer the reader to [1] for a good review on the theory and applications of wavelets in face recognition. In this chapter we will concentrate on some new transforms that have emerged from the limitations in wavelets. First, we will outline the limitations of wavelets and show how the new image analysis tools overcome them. Next, we review some of the existing work in face recognition that has benefited from using these tools. Finally, we show how these new tools fit into the larger, newly developing arena of signal processing known as Compressive Sampling or Compressed Sensing (CS). We outline how CS can be used for face recognition which certainly will be a new direction in the field of face recognition.

Combining Wavelets with HMM for Face Recognition
This paper describes face recognition algorithms that improve upon the original DCT based HMM face recogniser by using wavelet multiresolution analysis to extract observation sequences . In this approach a face image is divided into a number of overlapping subimages and wavelet decomposition is performed on each of the subimages. The ORL and our own face databases are used to test the algorithm...
متن کاملMultiresolution face recognition
In this paper the contribution of multiresolution analysis to the face recognition performance is examined. We refer to the paradigm that in classification tasks, the use of multiple observations and their judicious fusion at the data, feature or decision level improves the correct decision performance. In our proposed method, prior to the subspace projection operation like principal or indepen...
متن کاملA comparative study in wavelets, curvelets and contourlets as feature sets for pattern recognition
There have been a number of recent works in computer vision that had used new age multiresolution multidirectional transforms like curvelets and contourlets for face and character recognition. Although these works produced high recognition accuracies they did not provide any comparative study against more well known techniques and hence could not justify the use of these new transforms as again...

متن کاملFace Recognition by Curvelet Based Feature Extraction
This paper proposes a new method for face recognition based on a multiresolution analysis tool called Digital Curvelet Transform. Multiresolution ideas notably the wavelet transform have been profusely employed for addressing the problem of face recognition. However, theoretical studies indicate, digital curvelet transform to be an even better method than wavelets. In this paper, the feature ex...
