With the development of digital images processing, image inpainting is become one of the most impressive and useful technique. Based on partial derivative equations or texture synthesis, many image inpainting techniques have been proposed. Amano et al. proposed a method that based on eigenspace analyzes, which is called Back Projection for Lost Pixels (BPLP). It obtains the eigenspace from a set of...
Euler angles play a vital role in diffusion tensor imaging (DTI) which has received intensive attention recently. However, different Euler angle conventions generate different rotation paths, whereas in some applications it is desirable to obtain a unique rotation path. This paper applies Euler angle rotations to diffusion tensor magnetic resonance imaging, explains in detail the conversion between...
This paper studies and evaluates the feasibility and the performance of different level interpolations for improving spatial resolution of diffusion tensor magnetic resonance imaging (DT-MRI or DTI). In particular, the following techniques are investigated: anisotropic interpolation operating on scalar gray-level images, log-Euclidean interpolation method, and the quaternion interpolation method,...
This paper studies two levels of interpolation techniques for improving spatial resolution of diffusion tensor magnetic resonance imaging (DTI): a) at the level of scalar gray-level images using anisotropic interpolation and b) at the level of diffusion tensor fields using Log-Euclidean interpolation and quaternion interpolation. The performance of these different level interpolations is evaluated...
Diffusion tensor magnetic resonance imaging (DT-MRI, or DTI) is a new technique allowing ex-vivo and/or in-vivo investigation of human fibrous tissues. Processing of DT-MRI data appears as a new field for image processing community. This paper presents an interpolation method for the eigenvector fields in human cardiac DT-MRI. The method accounts for inherent relationships between vector components...
Computing-intensive algorithms which occupy most of executing time are always the main bottleneck in real-time or high quality video applications. In this paper, the optimization methods of the computing-intensive decoding algorithms of H.264, including MC (Motion Compensation), Deblocking and IDCT-IQ (Inverse Discrete Cosine Transform-Inverse Quantization), are proposed firstly, and then implemented...
