基于Android平台的图像预处理系统的研究

RESEARCH ON IMAGE PREPROCESSING SYSTEM BASED ON ANDROID PLATFORM

目前,Android是应用最广泛的开源手机操作系统,然而Android系统自身的图像处理能力相对有限。因此,本文在Eclipse下,采用Android SDK编译技术在Android平台上实现了图像预处理系统,主要实现获取图像、图像处理、调节图像等功能,图像处理包括灰度图像,平滑图像,锐化图像以及边缘检测,图像调节包括饱和度、色相、亮度的调节。最后,将采集到的图像实时、快速的处理,既能减少所占内存大小又不丢失图像所包含信息,节省了将图像上传服务器时所消耗的流量又不影响后续的处理。

At present,the Android is the open source mobile operating system which is the most widely used. However,the function of Android image processing is relatively limited. So,the paper adopts Android SDK compilation to achieve the system of image preprocessing in the Eclipse. Image preprocessing mainly realizes image capturing,image processing and image adjustment and so on. Image processing includes grayscale image,smooth image,sharpen image and edge detection. Image adjustment chief regulates saturation,hue and brightness. Finally,the captured image which can fast process in time both reduce the memory size and not lose the image information. As the same time,the system not only saves traffic that is consumed by the uploaded image to server but also not affect the subsequent processing.
