Description: This a camera calibration toolbox for generic lenses. The toolbox can be used to calibrate conventional,
wide-angle and fish-eye lens cameras. The calibration is based on viewing a planar calibration object.
The intrinsic and extrinsic camera parameters are estimated from control point correspondences between
the calibration plane and calibration images. This toolbox is a result of research that has been carried out
in the Laboratory of Computational Engineering at Helsinki University of Technology and
in the Machine Vision Group at University of Oulu.

Description: This paper presents a clustering approach
which estimates the specific subspace and the intrinsic dimension of each class. Our approach
adapts the Gaussian mixture model framework to high-dimensional data and estimates
the parameters which best fit the data. We obtain a robust clustering method called High-
Dimensional Data Clustering (HDDC). We apply HDDC to locate objects in natural images
in a probabilistic framework. Experiments on a recently proposed database demonstrate the
effectiveness of our clustering method for category localization. Platform: |

Description: A multi-dimensional ensemble empirical mode decomposition (MEEMD) for multi
dimensional data (such as images or solid with variable density) is proposed here. The
decomposition is based on the applications of ensemble empirical mode decomposition
(EEMD) to slices of data in each and every dimension involved. The final reconstruction
of the corresponding intrinsic mode function (IMF) is based on a comparable minima
scale combination principle. Platform: |

Description: 地震勘探采集的地震数据一般以地震道为单位进行组织,采用SEG-Y文件格式存储。SEG-Y格式是由SEG (Society of Exploration Geophysicists)提出的标准磁带数据格式之一,它是石油勘探行业地震数据的最为普遍的格式。读取数据后经过处理可以得到有关地下构造和岩性等大量有用信息信息。但是原始数据数据量庞大而且杂乱无章,为了使大量的数据变得直观、易于理解,揭示数据间的内在联系,必须对原始数据经过一系列变换转换成图形图像,将信息以更容易理解的形式展现出来。VC++功能强大、界面友好且操作方便,因此目前PC机上通常在VC++环境下对这种格式存放地震勘探数据进行处理并实现可视化显示。笔者在做地震数据可视化时利用VC++6.0编写了地震数据的读取处理程序及绘图程序。-Seismic exploration seismic data acquired seismic traces generally organized as a unit, using stored SEG-Y file format.

But the huge amount of data and disorganized the raw data in order to make large amounts of data becomes intuitive, easy to understand, reveals the intrinsic link between data must go through a series of transformations of the original data is converted into graphic images, the information in a more easily understood form of show come out.

Description: Texture-Aware Fast Global Level Set Evolution-Due to its intrinsic advantages such as the ability to automatically handle complex shapes and topological changes, the level set method has been widely used in image segmentation. Nevertheless, in addition to be computational expensive, it has the limitation to very often lead to a local minimum because of the energy functional to be minimized is non-convex. In this work, we use the geometric active contours and the image thresholding frameworks to design a novel method for global image segmentation. The local lattice Boltzmann method is used to solve the level set equation. The proposed algorithm is therefore effective and highly parallelizable. Experimental results on satellite, natural and medical images demonstrate the effectiveness and the efficiency of the proposed method when implemented using an NVIDIA graphics processing units
The present Matlab code is the implementation of our work.
For using:
