  • two-dimension code
    说明:  QR二维码识别中在对图像预处理后最重要的一步就是要进行定位,QR二维码中有三个位置探测图形,通过扫描其特征便可以进行精细定位,提出了一种新的算法用于筛选候选点。(In QR code recognition, the most important step after image preprocessing is to locate. There are three position detection patterns in QR code, which can be precisely located by scanning its features. A new algorithm is proposed to screen candidate points.)

  • sharpen
    数字图像处理中的平滑和锐化(边缘检测)。包括1、添加椒盐、高斯噪声。2对噪声污染的图像分别使用邻域平均法、中值滤波法、K邻近平均法进行平滑。3对一幅图像利用Roberts梯度法、Sobel算子和拉普拉斯算子进行锐化,并比较结果。附处理源图像和处理结果截图。 (Digital image processing smoothing and sharpening (edge detection). Including 1, add salt and pepper, Gaussian noise. Two pairs of images were used noise pollution neighborhood average, median filtering, K close to the average method to smooth. 3 on an image using Roberts gradient method, Sobel operator and Laplacian sharpening, and compare the results. Laws dealing with the source image capture and processing results.)

  • read_ENVIimagefile
    说明:  ENVI软件标准格式的高光谱遥感图像含有两部分:一个是高光谱图像 '*.img ',另一个是遥感图像头文件 '*.hdr',该文件记录了遥感图像的信息,如图像尺寸、波段数、数据类型和大小端等。如果缺少头文件,将无法对遥感图像进行读取,因此头文件十分重要。 在Matlab中,将利用函数multibandread()对多波段(高光谱/多光谱)图像进行读取。(The hyperspectral remote sensing images of ENVI software standard format contain two parts: one is hyperspectral image'*.img ', the other is the remote sensing image header file'*.hdr', which records the information of remote sensing image, such as image size, band number, data type and size end, etc. If there is no header file, it will not be able to read remote sensing images, so header files are very important. In Matlab, multibandread () is used to read multiband (hyperspectral / multispectral) images.)
