The classification accuracy of a remote sensing image should be assessed before the result is used for scientific investigation and policy decision. We proposed an assessment model based on spatial sampling to reflect region sensitivity image. aims solve following problems: (1) what size selected assessment; (2) where sample points distributed in region; (3) how analyze assessment. This was gray-level co-occurrence matrix (GLCM) considered both calculation distribution during overall kappa...
Aquaponics is an emerging area of agricultural sciences that combines aquaculture and hydroponics in a symbiotic way to enhance crop production. A stable smart aquaponic system requires estimating the fish size real time. Though deep learning has shown promise context aquaponics, most systems are extremely slow costly cannot be deployed on large scale. Therefore, we design present novel neuromorphic computer uses spiking neural networks (SNNs) for not only length but also weight fish. To...
Portable articulated coordinate measuring machine (PACMM) is a kind of high accuracy measurement instrument and it has been widely applied in manufacturing assembly. A number key problems should be taken into consideration to achieve the required accuracy, such as structural design, mathematical model calibration method. Although classical kinematic PACMM Denavit-Hartenberg (D-H) model, representation D-H encounters badly-conditioned problem when consecutive joint axes are parallel or nearly...
The typical nonorthogonal coordinate measuring machine is the portable (PCMM), which widely applied in manufacturing. In order to improve measurement accuracy of PCMM, structural designing, data processing, mathematical modeling, and identification parameters are essential for accuracy, should be taken into account during development. this paper, a kind PCMM used detecting crucial dimension automobile chassis has been studied calibrated. Denavit–Hartenberg (D–H) kinematic modeling method...
An increasing number of unknown islands, an important resource for human development, is identified based on segmentation remote sensing image. Different from traditional digital image, image has significant characteristics, such as multi-band, multi-source, and multi-granularity. Thus, the theory not suitable Here, algorithm (Otsu), which a common method was improved in two aspects: (1) Based PCA band fusion, Otsu with one-dimensional extended to multi-dimensional ones; (2) By optimizing...
With the development of pervasive computing and mobile learning technology, it is an inevitable trend for teaching to extend out classroom. MOOC research hotspot in field online education, difficult avoid cheating examinations. SPOC from a kind new force, which easy realize integration with traditional university course, cultivate capacity necessary college students "Internet +" era. Therefore, SPOC-based course model proposed, finally, specific application examples results are presented....
This paper provides an effective content-based web image searching engine based on SIFT (Scale Invariant Feature Transform) feature matching. descriptors, which are invariant to scaling and transformation rotation, partially illumination changes affine, present the local features of image. To decrease unavailable matching, a dynamic probability function replaces original fixed value determine similarity distance database from training images. Then, by using pretreatment source images,...
The stocks are affected by various factors, and studies have shown that companies in the same industrial chain or with attributes more closely related, their share prices influenced each other. In financial field, this kind of stock correlation can provide good investment suggestion. previous method is investors analyze company's relationship, industry trading information, then define degree relevance between companies. However, approach subjective lack statistical evidence. paper, we...
MOOC is a hot topic in online education research. However, has less application school education. Only when applied into can be filled with strong and vigorous vitality, promote the reform development of teaching situations, models assessment methods Because poor control MOOC, SPOC utilized to achieve better controllability by combination classroom credits. In order play advantages fully, this paper presents SPOC-based path for university course , which described every step, then describes...
Abstract Traditional transmission line design often relies on human experience and is highly subjective. In order to realize intelligent route optimization, this paper the established geographic information system platform, selects 119°14’50” east longitude 119°17’56” longitude, 31°57’34” north latitude 31°54’49 latitude. For rectangular area of”, first rasterize into a 20*20 grid according rasterization model, then enter coordinates of avoidance area, optimize shortest path ant colony...
