	Abstract:3D reconstruction is an important technique in the domain of computer vision. The existing systems of 3D reconstruction are often built on specialized hardware such as structured light or laser scanner with high cost. And some systems require intricate calibration procedures using complex calibration objects. These are not practical to reconstruct the 3D model of an arbitrary scene. In this paper, a flexible method of 3D reconstruction based on uncalibrated image sequence is proposed. This proposed system consist a series of processes such as feature points extraction and match, projective reconstruction, self-calibration, dense match, and finally the dense surface of 3D model can be reconstructed. Experimental results prove that this method is practical and has higher precision.

	Abstract:Conventional 2-D discrete cosine transform (DCT) and 2-D discrete wavelet transform (DWT) don’t take image orientation information into account. Thus it becomes a key issue that how to incorporate the image orientation information into DCT and DWT for some special applications. At the same time, with the development of the ultrasonic imaging, it has become an important means of medicine diagnosis. However, speckle noise is produced in the process of the ultrasonic imaging, and it degrades the quality of the image. It is also a key issue that how to remove the speckle noise. Based on the above two issues, aiming at the sectorial ultrasound image, according to the characteristic of its emission wave of the probe of an ultrasonic machine, the paper proposes directional DCT-DWT hybrid transform, the hybrid transform is used to denoise the ultrasound image, the experiment result shows that the proposed algorithm obtained good denoise effects.
