Research Highlights: This paper proposes a new method for hemispherical forest canopy image segmentation. The is based on deep learning methodology and provides robust fully automatic technique the segmentation of photography (CHP) gap fraction (GF) calculation. Background Objectives: CHP widely used to estimate structural variables. GF most important parameter calculating leaf area index (LAI), its calculation requires binary result CHP. Materials Methods: Our consists three modules,...

Recent years have witnessed a renewed interest in reinforcement learning (RL) due to the rapid growth of Internet Things (IoT) and their associated intelligent information processing decision-making demands. As slow speed is one major stumbling blocks classic RL algorithms, substantial efforts been devoted developing faster algorithms. Among them, post-decision state (PDS) prominent one, which can often improve by orders magnitude exploiting structural property underlying Markov decision...

Data input within mixed reality environments poses significant interaction challenges, notably in immersive visual analytics applications. This study assesses five numerical techniques: three benchmark methods (Touch-Slider, Keyboard, Pinch-Slider) and two innovative multimodal techniques (Bimanual Scaling, Gesture Voice). An experimental design was employed to compare these techniques’ efficiency, accuracy, user experience across varying precision distance conditions. The findings reveal...

Hand bone age, as the biological age of humans, can accurately reflect development level and maturity individuals. Bone assessment results adolescents provide a theoretical basis for their growth height prediction. In this study, deep convolutional neural network (CNN) model based on fine-grained image classification is proposed, using hand dataset provided by Radiological Society North America (RSNA) research object. This automatically locate informative regions extract local features in...

Abstract Background Clinically, doctors obtain the left ventricular posterior wall thickness (LVPWT) mainly by observing ultrasonic echocardiographic video stream to capture a single frame of images with diagnostic significance, and then mark two key points on both sides ventricle their own experience for computer measurement. In actual measurement, doctor’s selection point is subjective, difficult accurately locate edge, which will bring errors measurement results. Methods this paper,...

We present the prototype of an egocentric vision based assistive co-robot system. In this system, user is wearing a pair glasses with forward looking camera, and actively engaged in control loop robot navigational tasks. The serve for two purposes. First, it serves as source visual input to request find certain object environment. Second, motion patterns computed from video associated specific set head movements are exploited guide object. These especially helpful quadriplegic individuals...

Abstract Maize ( Zea mays L.) is one of the main food crops in China but problems with lodging have seriously affected quality and production. In this study, resistant density tolerant varieties maize were screened. The relationships between rind penetration strength (RPS), stalk breaking (SBS), yield under two different planting densities studied. Eight hybrid combinations set up 75,000 90,000 plants ha –2 their effects on determined a regression equation method. results showed that had...

A limitation of present elastic metasurfaces remains in their modest flexibility to meet convertible functions on demand. Here, a feasible single-layered lossless metasurface is theoretically proposed and experimentally demonstrated for adjusting the asymmetric transmission flexural waves. The easily reconstructed unit derived from multiple pillared resonators; then, number units per period can be changed depending desired integer parity. In addition, physically realized by uneven...

Abstract The Warren and Root (1963) transfer function laid the foundation for describing mass between matrix fracture blocks in dual-porosity (DP) reservoir simulation. However, pseudo steady-state (PSS) assumption imbedded approach of is no longer applicable when duration transient state prominent (tight oil or shale gas reservoirs). Lim Aziz (1995) derived new shape factors a framework that avoids PSS assumption. similar to formulation Root, approximation fails capture pressure gradients...

Skin colour has a potential connection to facial impressions. For CG (computer graphics) character designing, tuning the skin build required is vital procedure. The previous findings provide essential suggestions an attractive face, but are still insufficient for Artificial Intelligence (A.I.) system characters with different personalities and present study investigates relationship between multiple categories of impression attributes based on psychophysical experiment. Four attributes,...

Facial skin colour, a key factor related to impressions, is widely used by CG character designers build characters with different storylines. The previous research provided essential suggestions for creating an attractive facial image. However, the of prior are insufficient building resonate current public, especially young people. present study investigates influence colour (whiteness and hue angle) on femininity, masculinity likableness perception Chinese female male images.
