Group-based atrous convolution stereo matching network
Stereo matching, is the key technology in stereo vision. Given a pair of rectified images, stereo matching determines correspondences between the pair images and estimate depth by obtaining disparity between corresponding pixels. Current work has shown that depth estimation from a stereo pair of images can be formulated as a supervised learning task with an end-to-end frame based on Convolutional Neural Networks (CNNs). However, 3D CNN makes a great burden on memory storage and computation, which further leads to the significantly increased computation time. To alleviate this issue, atrous convolution was proposed to reduce the number of convolutional operations via a relatively sparse receptive field. However, this sparse receptive field makes it difficult to find reliable corresponding points in fuzzy areas, e.g., occluded areas and untextured areas, owning to the loss of rich contextual information. To address this problem, we propose Group-based Atrous Convolution Spatial Pyramid Pooling (GASPP) to robustly segment objects at multiple scales with affordable computing resources. The main feature of GASPP module is to set convolutional layers with continuous dilation rate in each group, so that it can reduce the impact of holes introduced by atrous convolution on network performance. Moreover, we introduce a tailored cascade cost volume in a pyramid form to reduce memory, so as to meet real-time performance. Group-based atrous convolution stereo matching network is evaluated on the street scene benchmark KITTI 2015 and Scene Flow and achieves state-of-the-art performance.</div
Patterned Manipulated Surface Based on Femtosecond Laser with Adjustable Wetting Speed and Directional Fluid Delivery
Recently, due to the crucial roles
of multifunctional liquid manipulation
surfaces in biomedical transportation, microfluidics, and chemical
engineering, the demand for controllable and functional aspects of
directed liquid transportation has increased significantly. However,
designing an intelligent manipulation surface that is easy to manufacture
and fully functional remains an immense challenge. To address this
challenge, a smart surface that can regulate the rate of liquid transport
within a patterned channel by temperature is reported. A synergistically
controlled approach of poly(N-isopropylacrylamide)
and micropillar shape-memory polymers (SMPs) was used to modulate
the wetting rate of liquids on surfaces. By femtosecond laser direct
writing, temperature-responsive composite surfaces are embedded in
the microstructure of shape-memory polymers (SMPs) in a patterned
manner, resulting in the preparation of novel programmable liquid
manipulation surfaces incorporating boundaries possessing asymmetric
wettability. Since the smart surface is based on SMP, the superhydrophobic
part in the superhydrophobic/controllable wettability patterning platform
is also programmed for droplet directional transport, which takes
advantage of the difference in wettability between the rewritable
indentation track and the periphery to allow droplets to flow into
the temperature-controlled velocity track, enriching the functionality
of the surface. In addition, based on its excellent controllability
and patterning, the surface has been shown to be used in microfluidic
circuit chips with self-cleaning properties, which provides new ideas
for circuit timing control. This study provides promising prospects
for the effective development of multifunctional liquid steering surfaces,
lab-on-a-chip, and microfluidic devices
