    A novel and convenient multi-camera self-calibration method is proposed in this paper. Different from other calibration methods, our method is done by analyzing human body motion. The only constraint is that several people of different heights are needed to walk around the experimental environment one by one in the calibration period. By this way, two kinds of corresponding points are extracted fr... View full abstract»

    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (661 KB) | HTML iconHTML

    In a digital watermarking scheme, it is not convenient to carry the original image all the time in order to detect the owner's signature from the watermarked image. Moreover, for those applications that require different watermark for different copies, it is preferred to utilize some kind of watermark-independent algorithm in extraction. This paper presents a digital color image watermarking schem... View full abstract»

    Motion Compensated Frame Interpolation (MCFI) is a commonly used method to enhance the temporal resolution of video sequences. However, when scene change occurs, there is less temporal correlation between frames, so the interpolation technique can't work well. Moreover, this motion-based method always induces visual artifacts due to incorrect motion vectors. In this paper, firstly a scene change d... View full abstract»

    A quality prediction model for images coded with JPEG is proposed in this paper. This model estimates the quality of an image at a given compressed ratio based on the structural similarity theory, without actual coding of the image. As different frequencies play various roles in human vision, the frequency sensitivity-based structural similarity model is introduced in this paper. The proposed mode... View full abstract»

    Aiming at the difficulty of choosing filtering parameters of Non-Local Means (NLM) denoising algorithm for Cone-Beam Computed Tomography (CBCT) projection images, an adaptive NLM denoising algorithm is proposed. First, a simplified noise estimation method based on sub-block division is proposed to replace the approach of designating the background region, which can adaptively identify the backgrou...

    This paper presents a novel camera calibration method for a system consists of a sensor-less mobile robot and an external camera. This method can estimate the focal length and the viewing direction of the camera relative to a plane where the sensor-less mobile robot moves from a single image of an arbitrary circle on that plane. Since it is easy to let a four-wheel mobile car to move along a circu... View full abstract»

    Reduced-reference (RR) image quality assessment metrics (IQA) evaluate the quality of images by extracting a parameter set from the original reference image and using this set in place of the actual reference image. In this paper, we propose a novel RR-IQA metric based on Contourlet transform. By combining Contourlet transform with a version of the hidden Markov model - Gaussian scale mixtures (GS...

    In this paper, we are interested in the problem of motion-blurred image blind restoration. A new method for this ill-posed problem is proposed. We present an adaptive Huber Markov Random Field (HMRF) image prior model as the regularization term, which can be suitable for motion-blurred situation, then turn the ill-posed problem to well-posed. It can preserve fine image details and edges. However, ... View full abstract»

    Based on image content, a new watermarking robust algorithm were presented in this paper. A region formed by feature points of the image is used to embed mark. The feature points and region eliminate the effect of geometric distortion, Experiments demonstrate that the technique can well withstand attacks such as rotating, scaling and JPEG lossy compression.

    In order to improve the properties of directionality, frequency band partition, and shift-invariance of the classical two-band discrete wavelet transform, we propose a new wavelet transform construction by concatenating 2D M-band undecimated wavelet transform with undecimated checkerboard-shaped filter banks in this paper. In the 2-D case, it provides one lowpass subband and 2(M2-1) directional hi... View full abstract»

    In this paper, we improve the soft-threshold by using Markov random field (MRF) theory to preserve the edges of images. According to MRF theory, the similarity problem of the edge structure can be transformed into an energy function minimization problem. Through computing all the energies of the edge structures in clique c, we can find the edge structure with the minimum energy, and regard it as t... View full abstract»

    The paper presents an adaptive image deblurring method with ringing control. Images are split in analogy with unsharp mask into low- and high-frequency components. Edges are sharpened in low-frequency domain using deconvolution with Total Variation constraint. High-frequency information is amplified using ringing level control. View full abstract»

    Color constancy is the ability to remove the dependency of illuminant and show the intrinsic color of objects. A novel multi-view video coding scheme integrated with color constancy algorithms is introduced in this paper. Color constancy algorithms based on gray-edge hypothesis are selected. The new scheme takes color constancy as a preprocessing to make the sequence independent of the illuminant ... View full abstract»

    This paper presents the design and implementation of an approach to creating a single-viewpoint full view panorama photograph from a set of image sequence. To ensure the simplicity for both shooting and stitching, input images are individual frames extracted from a panning video sequence. The ordered approach also proves to be computationally less expensive than the case where input images are dis... View full abstract»

    Finger-vein recognition has been considered as one of the most convenient and effective biometric ways for personal identification. Extracting vein characteristics is crucial for finger-vein classification. However, the finger-vein extraction results always are greatly sensitive to noises due to the low contrast of finger-vein images. To robustly exploit real vein information, this paper proposes ...
