Run the fuliye_xiangguan.m file directly, the program comes with the letters in the picture 2222.PNG IJ character positioning. And displays the results in the form of bright spot in another black background picture and spot exactly corresponds to the position where the IJ in the original picture appears. The code primarily using Fourier transform and inverse transform, the physical idea of the code comes from 4F optical joint transform correlator, which is the essence of digital simulation, is equivalent to an optical experiment platform using the filter-related bright spots experiment. Code rot90 (a,2) this operation is to make the target characters flipping, this one is necessary. Thresh in the code =25 the range of this value is derived from the C1 data, in General, take the maximum value of thresh is slightly smaller than C1 and thresh the greater the blobs obtained less. Thresh is smaller, get more bright spots, of course we do not want this to happen

MATLAB control automatic time-lapse camera-GUI sou

In the MATLAB interface operating Guide, open the monitor.Fig file in the pop-up window, provided that the monitor.Fig and monitor.m files are put together, or error. After you run a fig file, see time-lapse parameters in the interface, the default is 10 seconds to take a picture. Interface in addition to automatic shooting, and manual shooting modes, click on ' manual shots. Shoot the picture does not meet everyone's requirements, provided the image is in the statement obj = videoinput (\'winvideo\',2,\'YUY2_640x480\'); \'YUY2_640x480\' for 640x480 of photograph pixels in images. MATLAB also supported formats are \'YUY2_160x120\' \'YUY2_176x144\' \'YUY2_320x240\' \'YUY2_352x288\' \'YUY2_640x480\', according to their own needs to adjust picture size.

In the MATLAB2012 version, execute the show1.m and show2.m file, distribution of feature points by the two images and description, and in order to accelerate the running speed, the result D1,D2,K1,K2, mat is stored in the hard disk. Information about the two images have been last run match.m, two related points, the match between picture and lines connected. Other m-files for the SIFT algorithm m code files, including Gaussian differential pyramid algorithm dog.m-. Local_max.m-algorithm for image feature points in the key points, which reached the maximum worth. Descriptor.m-descriptor generation algorithm. I buttoned 1104992692, if you have problem with using, welcom to communion, open source

Optical character recognition (OCR) optical character recognition an m program has more than one callback function. After you run the main program to achieve target object is locked to the picture, and extraction. And from the ABC library functions with the corresponding letters are displayed
