摘要:
 在Android移动应用中,图片传输是造成用户网络数据流量消耗的主要原因之一。虽然高效的图片压缩方法是解决该问题的有效途径,但是目前在Android平台上的图片压缩方法还未得到广泛研究。文中采用Android API对图片进行压缩预处理,并对预处理图片进行颜色转换、FDCT变换、量化、编码等操作,实现了在Android平台下的JPEG图像压缩编码过程,达到了在Android移动应用开发中对图片快速高效的压缩处理的目的。实验测试结果表明,该方法能够高效地压缩图片,在保证较高图像压缩比的同时,又能获得良好的图像质量。
Abstract:
 In the Android mobile applications, transferring pictures is the main reason that users consume their network data flow. Al-though efficient image compression method is an effective way to solve the problem,the image compression method does not be exten-sively studied on the Android platform. Pre-process the image with Android API before compressing image,and accomplish the process-ing of the pretreatment image’ s color conversion,FDCT transform,quantization,coding and other operations to achieve the processing of JPEG image compression encoding under the Android platform. The experimental results show that the method can efficiently compress images,and guarantee higher compression ratio and good image quality.
