Highly viable seeds are of great significance for agricultural development, and the traditional corn seed vigor detection method is time-consuming laborious. In this paper, spectral image information hyperspectral imaging was used, a distinction between prediction proposed. The potential technology convolutional neural networks (CNNs) to identify predict maize vitality evaluated. in 10 hours before germination four level (144 samples each) collected. A support vector machine, extreme...

Abstract Hyperspectral imaging technology was applied to detect and recognize six different varieties of Longjing fresh tea. The data contained image spectral information at 370–1042 nm; color texture features were the foci research. Spectral pre‐processing performed by multiplicative scatter correction (MSC) standard normal variate (SNV), then, we selected corresponding position variable vegetation indexes as features. Representative including most chose principal component analysis (PCA)....

The paper presents a facial expression recognition approach based on wavelet transform features and neural network ensemble classifier for the six basic expressions from static images of CMU-PITTSBURGH AU-Coded Face Expression Image Database. Because information are mostly concentrate regions, so mouth, eye eyebrow regions segmented firstly. Then low-dimension using Karhunen-Loeve acquired. A Bagging is constructed finally. proposed has demonstrated superior performance compared to networks....

Facial expression recognition is necessary for designing any human-machine interfaces. A novel facial method based on the Wavelet energy feature and neural network ensemble classifier proposed in this paper. And six basic expressions - anger, disgust, surprise, happiness, fear sadness are analyzed. Firstly, wavelet transform used static images extracted from various sub-areas as features; Secondly, Bagging algorithm to offer trainings recognition. Experiments results demonstrate an...

In this paper, a license plate location algorithm, fused texture characteristics and color information are proposed, where the of structure based on fixed collocation between background character plate. Firstly, we would perform edge detection gray-scale images vehicles, then, give Canny operator threshold algorithm about vehicle image. Secondly, detect number jump points each row, set to retain those lines greater than threshold, then test pixels retained. The region can be saved as area if...

In the light of problem monitoring forest fire, design strategy and practical implementation establishing fire system based on digital image information are proposed. The is continuous sampling provided by CCD camera. We can obtain configuration characteristics, dynamic characteristics color interesting region with an application processing algorithm, then to identify source according acquired characteristics. experimental results show that accurately confirm fire. Besides, amount data...

In order to get a higher recognition accuracy of gaits, gait system based on SVM and acceleration is proposed in this paper. The data are obtained from acquisition AT90CAN128 four accelerometers that attached human's thigh shank. Acceleration includes gaits which consist sitting, standing, walking going upstairs. After normalization median filtering used for data, GA applied recognition. overall more than 90%. Proved by the results experiments, whose parameter C g selected an effective approach.

(1) Background: Public space is an important carrier for maintaining the cultural values of a village and production living customs villagers, but use rights boundaries are in unstable ambiguous state, it not completely open inclusive public space. The study aims to deepen understanding publicness traditional villages from perspective subjective objective combination, which reveals relationship between villagers’ behavior. (2) Methods: research established evaluation framework assessing...

Two-level hybrid fusion model of a multi-sensor data system, which fits the system intelligent control greenhouse, is presented. At first, local given to fuse information from different sensors use collect parameters greenhouse environment; then fused in improved Yager theory. Local and global results will be stored knowledge base expert system. This algorithm used recognize decision environment monitor Through collecting real-time fusing data, we can get precise all kinds time, it also able...

Testing method by velocity of stress wave is widely used in the nondestructive testing system strength wood-based panel.

We present a new approach for compressing interference multispectral remote sensing images. A rectangle region-of-interest (ROI) coding algorithm is integrated with an embedded-block-coding optimized truncation (EBCOT) method to make distortion tracking of the spectral region. Accordingly, rate-distortion optimizer designed give adaptive lifting slopes. This allows peak signal-to-noise ratio (PSNR) reconstructed region be guaranteed higher than 38 dB different image conditions. In this...
