提取糖尿病视网膜病变眼底图像上硬性渗出。将彩色图像转为灰度图,对灰度图进行形态学处理、去背景、阈值分割,最终将原图上的硬性渗出区域用绿色标记出来。(this word is to extrac the hard exudates on diabetic retinopathy fundus image. The color image to grayscale on grayscale morphological processing to the background, threshold segmentation, ultimately on the original hard exudates area marked in green.)
说明: LSB(英文 least significant bit)即最低有效位。LSB加密是信息隐藏中最基本的方法。由于人们识别声音或图片的能力有限,因此我们稍微改动信息的某一位是不会影响我们识别声音或图片的。(LSB replace steganography)
合成孔径雷达(SAR)成像的距离徙动校正(Synthetic aperture radar (SAR) imaging distance migration correction)
基于DCT的jsteg图像隐写及分析算法,MATLAB实现。 JSteg的算法主要思想是将秘密消息嵌入在量化后的DCT系数的最低比特位上,但对原始值为O、1的DCT系数不进行嵌入。提取秘密消息时,只需将载密图像中不等于0、l的量化DcT系数的LSB取出即可。(The main idea of the JSteg algorithm is to embed secret messages in the lowest bit of the quantized DCT coefficients, but the DCT coefficients of the original values are O and 1 are not embedded. When extracting secret messages, only the LSB of the quantized DCT coefficients not equal to 0 and l in the encrypted image can be taken out.)
Jsteg隐写算法[23][24]由D. Upham提出,该算法将秘密信息嵌入在量化后的DCT系数的LSB上,但值为-1、0、+1的DCT系数例外。提取秘密信息时,也只是将隐藏信息的图像中不等于-1、0、+1的量化DCT系数的LSB取出即可(steganography of jsteg)
