A neural-architecture search algorithm based on a voting scheme was proposed to address the difference between network architectures that are automatically searched by existing algorithms and those that were evaluated by the algor

This study proposes an underwater enhancement algorithm based on color balance and multi-scale fusion to address the color deviation， detail blur， and low contrast of underwater images caused by water absorbing and scattered light

Due to the small differences in image features between classes and the relative fuzzy classification threshold of retinopathy， automatic classification algorithms are challenged by problems related to low recognition and classific

To obtain the optical images of space targets with higher resolution and clarity， it is necessary to perform super-resolution reconstruction on the degraded images corrected by ground-based adaptive optics （AO） imaging telescopes.

Workpiece rotational grinding is the primary machining process for the bare wafer flattening and pattern wafer back-thinning of large silicon wafers. However， the grinding process inevitably causes surface and subsurface damage on

Traditional methods for generating beams with a long depth of focus， such as spatial light modulator and a combination of positive and negative lens， have several limitations， including a large size of optical elements， difficult

This paper proposes a mini-piezo-element drive microactuator based on triangular amplification. The actuator is composed of two 1.6 mm×1.6 mm×5.0 mm mini piezo-elements， two triangular waists serving as symmetrical stretch arms， a

Gear helix deviation is an important index for evaluating gear accuracy class and bearing uniformity， and it is one of the four mandatory inspection items specified in the national standard for gear GB/T 10095.1-2008. The datum fo

Focusing on the problem of uncertainty in the traceability of free-form surface contours measured using a surface structured light scanner， two different uncertainty evaluation models were proposed. The transparent box model， base

The Io plasma torus is the most densest and most widely studied region of Jupiter's magnetosphere. To meet observe the Io plasma torus observation， a Lyot Coronagraph was installed in the planet's atmosphere spectrum telescope to

Owing to its high sensitivity and repeatability， optical interferometry is often used to measure geometric quantities， such as micro-displacement， with high accuracy. To achieve the accurate measurement of nanodisplacements， a lin

To accurately measure the thickness of the radial GRIN lens， the measurement error caused by eccentricity was studied. First， the working principle of the spectral confocal thickness measurement system was introduced. Then， the th
