Abstract

Guava leaves are healthy indicators for growth in a tree. The visual inspection of diseased area might mislead to inaccuracy for pruning. The leaves of guava are majorly elliptical or oval within the upper surface, and dull green in color. If the leaf diseased, it appears to be red or purple. There are number of pathogen might impact on any parts of its surface. In this paper, a total of four types of diseases namely: canker, dot, mummification and rust considered from the already available data set. The necrotic areas, perimeter, major axis and minor axis measured within the diseased area in its gray scale image. Additionally, shape descriptors used for analyzing the region of interest in diseased areas of dot, mummification and rust images.
用图像处理技术测定坏死区番石榴叶病的若干研究
番石榴叶是树木生长的健康指标。对患病区域的目视检查可能会误导修剪的准确性。番石榴的叶子上表面呈椭圆形或椭圆形,颜色为暗绿色。如果叶片患病,它看起来是红色或紫色的。有许多病原体可能影响其表面的任何部分。在本文中,从已有的数据集中,共考虑了四种类型的疾病,即:溃疡病,斑点病,干尸病和锈病。在其灰度图像中测量病变区域内的坏死区域、周长、长轴和短轴。此外,形状描述符用于分析斑点,木乃伊化和铁锈图像中病变区域的兴趣区域。
