Meanwhile  various factors cause the decline of image quality  and images must be enhanced in order to meet demands of doctor's clinical diagnosis. The general enhancement algorithms don't consider body's structure differences and density characteristics. A new adaptive CR enhancement algorithm was proposed in this article  and head and neck CR images were processed with this method and compared with linear unsharp masking method. The experiment proves that the details of CR image enhanced were abundant and enhanced CR image had good visual effect  SNR was high  as well as detail variance /background variance (DV/BV) indicating that this algorithm is suitable for head and neck CR medical images.

To render a full-color image  need an interpolation process commonly referred to as CFA demosaicking  is required to estimate the other two contributions for producing a full-color image. But  the noise in imaging sensors not only corrupts the color filter array  at the same time introduces artifacts during the color interpolation step and influence quality of images. In order to acquire high quality full-color images  adopt a sort of viable and effective interpolation algorithm based on gradient  at the time of removing the noise  reserve image border and detail information clearly. 2012 IEEE.   ACCURACY EVALUATION OF THE GROUND-BASED FRACTIONAL VEGETATION COVER MEASUREMENT BY USING SIMULATED IMAGES 会议论文  OAI收割 2012 Ieee International Geoscience and Remote Sensing Symposium, New York Zhao, Jiqiang; Xie, Donghui; Mu, Xihan; Liu, Yaokai; Yan, Guangjian 收藏  |  浏览/下载：32/0  |  提交时间：2014/12/07 Digital photography  FVC  physically based ray-tracing  simulated  images  accuracy evaluation  DIGITAL IMAGES
