Description: A novel distortionless image data hiding algorithm based on integer
wavelet transform that can invert the stego-image into the original
image without any distortion after the hidden data are extracted is
proposed. This algorithm hides data into one (or more) middle bitplane(
s) of the integer wavelet transform coefficients in the middle and
high frequency subbands. It can embed much more data compared
with the existing distortionless data hiding techniques and satisfy the
imperceptibility requirement. The image histogram modification is
used to prevent greyscales from possible overflowing. Experimental
results have demonstrated the validity of the algorithm Platform: |

Description: 采用 CAMSHIFT 算法快速跟踪和检测运动目标的 C/C++ 源代码，OPENCV BETA 4.0 版本在其 SAMPLE 中给出了这个例子。算法的简单描述如下-This application demonstrates a fast, simple color tracking algorithm that can be used to track faces, hands . The CAMSHIFT algorithm is a modification of the Meanshift algorithm which is a robust statistical method of finding the mode (top) of a probability distribution. Both CAMSHIFT and Meanshift algorithms exist in the library. While it is a very fast and simple method of tracking, because CAMSHIFT tracks the center and size of the probability distribution of an object, it is only as good as the probability distribution that you produce for the object. Typically the probability distribution is derived from color via a histogram, although it could be produced from correlation, recognition scores or bolstered by frame differencing or motion detection schemes, or joint probabilities of different colors/motions etc.
In this application, we use only the most simplistic approach: A 1-D Hue histogram is sampled from the object in an HSV color space version of the image. To produce the Platform: |

Description: his paper presents a reversible data hiding method based on wavelet spread spectrum and
histogram modification. Using the spread spectrum scheme, we embed data in the coefficients of integer
wavelet transform in high frequency subbands. The pseudo bits are also embedded so that the decoder does
not need to know which coefficients have been selected for data embedding, thus enhancing data hiding
efficiency. To prevent the overflow and underflow, an efficient histogram modification method is developed
and utilized. Experimental r-his paper presents a reversible data hiding method based on wavelet spread spectrum and
