摘要： 随着遥感影像获取技术的不断发展,遥感飞机的机型及位置检测成为检测重点。然而,由于其复杂的背景,不同的空间分辨率,姿态和光照变化复杂,导致检测精度不高。此外,本研究中遥感飞机的类内和类间方差都较大,给机型的识别增加了难度。为了提高算法对遥感影像目标的检测精度,本文提出一种基于YOLv4和TripleLoss的目标检测算法,首先运用Sobel算子和Mosaic对数据集扩充和增强;其次,用Triple Loss代替原有的分类损失函数来提高分类精度,最后通过实验验证本算法的有效性和准确性。

摘要： “假设一个普通人的阅读生涯可以持续60年，每一年阅读数量达到20本，他一辈子也只能读到1200本书，这个数字里还不算上重读的部分。我们想做的这种书店，就是为了真实解决这部分人的需求而存在。”书店老板的目标坚决而笃定，建筑师以此为基础进行设计。在经历过无数个掀翻屋顶的“头脑风暴”之后，在数不清的日夜加班之后，CalImeMOSAIC终于露出了真面容。

摘要： 虽然在日常图片和视频中我们经常会接触到马赛克,但很多人对它的由来可能并不清楚.“马赛克”是英文单词“mosaic”一词的音译,其本为一种源于古希腊的呈块状镶嵌工艺.而人们对图像进行区域性模糊处理的方法就是：将特定区域的色阶细化,并造成色块打乱的效果.这样的色块就像一个个小方格,与马赛克非常相似.因此,这种图像模糊处理就被称为“马赛克”.马赛克在我们的生活中起到了非常重要的保护作用.比如对一些涉及恐怖和血腥的内容,打个马赛克能避免对观看者造成不适.此外,马赛克也可以保护被采访人员的安全和肖像权.但问题在于,在人工智能时代来临之后,马赛克可能要面临被“解码”的风险了.

摘要： This paper aims to assess the ways in which multi-resolution object-based classification methods can be used to group urban environments made up of a mixture of buildings, sub-elements such as car parks, roads, shades and pavements and foliage such as grass and trees. This involves using both unmanned aerial vehicles (UAVs) which provide high-resolution mosaic Orthoimages and generate a Digital Surface Model (DSM). For the study area chosen for this paper, 400 Orthoimages with a spatial resolution of 7 cm each were used to build the Orthoimages and DSM, which were georeferenced using well distributed network of ground control points (GCPs) of 12 reference points (RMSE = 8 cm). As these were combined with onboard RTK-GNSS-enabled 2-frequency receivers, they were able to provide absolute block orientation which had a similar accuracy range if the data had been collected by traditional indirect sensor orientation. Traditional indirect sensor orientation involves the GNSS receiver in the UAV receiving a differential signal from the base station through a communication link. This allows for the precise position of the UAV to be established, as the RTK uses correction, allowing position, velocity, altitude and heading to tracked, as well as the measurement of raw sensor data. By assessing the results of the confusion matrices, it can be seen that the overall accuracy of the object-oriented classification was 84.37%. This has an overall Kappa of 0.74 and the data that had poor classification accuracy included shade, parking lots and concrete pavements. These had a producer accuracy (precision) of 81%, 74% and 74% respectively, while lakes and solar panels each scored 100% in comparison, meaning that they had good classification accuracy.

摘要： 近日,中国农业科学院植物保护研究所经济作物病毒病害研究团队与中国农业大学以及日本果树病毒专家合作,利用高通量测序技术从苹果花叶样品中鉴定出一种新的病毒,命名为苹果坏死花叶病毒[Apple necrotic mosaic virus（ApNMV）],并证实这种病毒跟我国苹果花叶病高度相关,颠覆了人们对苹果花叶病病原的常规认知.

摘要： Screening for the source of virus resistance in horticultural plants or specific characterization as hybridization, through symptoms, requires time and depends on the weather and knowledge of plant characteristics. So, it is important to develop specific gene markers to allow rapid diagnosis by PCR. Markers were developed based on sequences homology comparison of susceptible and resistant plants provided by HORTEC SEEDS in tomato for Tomato yellow leaf curl virus (TYLCV) by the resistance gene Ty-1, in zucchini for Zucchini yellow mosaic virus (ZYMV) and Papaya ringspot virus estirpe watermelon (PRSV-W), and in lettuce for Lettuce mosaic virus (LMV). Fragments of 249 bp were amplified only by resistant plants to TYLCV as the hybrids 2648 and Aguamiel, and not for varieties as Santa Cruz or Carina. It were observed for ZYMV the amplification of 791 bp by the resistant hybrid Px7051 and not for the susceptible cultivar La Belle;for PRSV-W using the same zucchini plants the amplification of 650 bp for susceptible and 750 bp for resistant;for LMV the 421 bp amplification only for the resistant cultivar Brasil 303 and not for susceptible Babá de Verão. Finally, it was observed that primers PK47F/R were able to check the Cabotiá seed hybrids of pumpkin Jabras.
