The reconstruction of high-dimensional sparse signals is a challenging task in wide range applications. In order to deal with problems, efficient fast Fourier transform algorithms are essential tools. second and third authors have recently proposed dimension-incremental approach, which only scales almost linear the number required sampling values quadratic arithmetic complexity respect spatial ...

Text detection has been significantly boosted by the development of deep neural networks but most existing methods focus on a single kind text instance (i.e., overlaid text, layered scene text). In this paper, we expand task from dimension to multiple dimensions, thus providing multi-type descriptions for and content analysis videos. Specifically, establish new detect classify instances simulta...

gamma camera is an important apparatus in nuclear medicine imaging. its detection part is consists of a scintillation detector with aheavy collimator. substitution of semiconductor detectors instead of scintillator in these cameras has been effectively studied. in this study, it is aimed to introduce a new design of p-n semiconductor detector array for nuclear medicine imaging. a p-n semiconduc...

Attention modulates visual processing along at least two dimensions: a spatial dimension, which enhances the representation of stimuli within the focus of attention, and a feature dimension, which is thought to enhance attended visual features (e.g., upward motion) throughout the visual field. We investigate the consequences of feature-based attention onto visual perception, using dual-task hum...

Path planning is indispensable in performing the inspection task using continuum robot in the environment like aircraft fuel tank. In order to obtain the optimal path and make it feasible for the robot traversal, a path planning strategy based on region division is put forward. The aircraft fuel tank is divided into several regions and mapped to a two-dimension plane by using dimension reductio...

Improving the spatial resolution in optical microscopes is a challenging task for many applications. In fluorescence confocal microscopy, the resolution is given by a lenght Detection Efficiency Function (DEF) which looks like a rice grain. 4Pi type C microscope has shown to be a powerful solution for considerably reducing the axial dimension of the DEF [1] and even its lateral dimension [2]. T...
