用MATLAB处理数字图像，对图像进行梯度处理，绘制图像的梯度图。(MATLAB deal with digital image, gradient image processing, rendering the image gradient map.)

张量投票算法,对连接断裂的线段有很好的效果(Tensor Voting)

几个图像中嵌入文本的LSB信息隐藏算法，适合信息隐藏初学者,注释详细(Several images embedded in the text of the LSB Information Hiding Algorithm for Information Hiding beginners, notes in detail)

能将一幅灰度图像根据用户自己给定的彩色图像将其对应的转化为真彩色图像。(Gray image can be processed into rgb image.)

求一个图像的最大内接矩形面积。 步骤： 1.相机标定。首先根据物像关系式求出其中的参数。注意参数求出后要进行参数校验。 2.从背景中分离出目标 3.边缘检测 4.目标形状参数计算。(For an image of the largest inscribed rectangle area. Steps: 1. Camera calibration. First of all object-image relationship in accordance with the parameters obtained. Attention to the parameters obtained after parameter calibration. 2. From the context of isolated target 3. Edge detection 4. Target shape parameters.)

粒子滤波与PHD多目标跟踪比较，三目标分别进行粒子滤波和marginalPHD滤波跟踪比较结果。(PHD particle filter multi-target tracking compared with the three goals were to filter tracking particle filter and marginalPHD comparison.)

图像质量评价指标：MSE，衡量融合图像相对于标准参考图像灰度的偏离程度。其值越小，说明复原图像和标准参考图像的差异越小，恢复效果越好。(Image quality evaluation MSE)

维纳滤波法去除加有高斯噪声、椒盐噪声、乘性噪声(Wiener filter method to remove the addition of Gaussian noise, salt and pepper noise, multiplicative noise)

这是一个实现各种颜色空间转换的程序，内含多种颜色之间的转换(this is a programme implementing color space transform,including many transforms of diffrent color spaces.)
