OpenCV function that finds BLOBS in a binary image with the help of the Grassfire algorithm. It is not recursive, but call the function Grassfire each time a white pixel is found in the image. Input: 8bit Unsigned Char binary image. Output: Ch

LSB（Least  Significant  Bit）算法是将秘密信息嵌入到载体图像像素值的最低有效位，也称最不显著位，改变这一位置对载体图像的品质影响最小。-LSB (further Significant Bit) algorithm is to embed the secret information carrier image pixel values of the Least Significant Bit, also known as the Least Signi
