In many image analysis and processing problems, discriminating the size and shape of each individual object in an aggregate pile projected in an image is an important practice. It is relatively easy t
In this paper, the regulatory role of ex-ogenous carbon monoxide (CO) during the genera-tion and development of adventitious roots in mung bean (Phaseolus radiatus L. cv. Mingguang) hypo-cotyl cutting
Magnetic Resonance Elastography (MRE) is a noninvasive technique to measure elas-ticity of tissues in vivo. In this paper, a mechanical shear wave MR imaging system experiment is set for MRE. A novel
It is very important to integrate remote sensing with urban geography that the spectral mix- ture analysis technique is applied to urban land cover evolvement and its eco-environmental effect. Urban l
Recent advances in 3D spatial data capture, such as high resolution satellite images and laser scanning as well as corresponding data proc- essing and modeling technologies, have led to the generation
Log polar transformation is an important algorithm of space-variant vision theory.It well depicts the retino-cortical mapping.Due to the logarithmic and the arctangent operation in the transformation,
This paper presents a robust color image hiding method based on YCbCr color system in discrete cosine transform (DCT) domain,which can hide a secret color image behind a public color cover image and i
Influenced by detectors material,manufacturing technology etc,every detector in infrared focal plane array (IRFPA) will output different voltages even if their input radiation flux is the same.And thi
We present a new multi-scale geometrical analysis method for ophthalmic image contrast enhancement based on the contourlet transform.The contourlet transform has better performance in representing edg
