Output: feature vector consisting color moment and the LBPī. Input: image where the feature vector will be findī. Each vector ranges in data size (between 10 and 20 cords) which causes issues when matching matrices of different sizes. If X and V are the same size and V only consists of true or. I have a vector containing a list of data (X and Y coords) which i want to compare to an array of 100 vectors (each with similar but not the same XY Coords) in order to find a match. Input: image where the histogram value of LBP feature will be find, the radius of the sampling pointsī. Indexing using vectors If X and V are vectors, then X(V) is X(V(1)), X(V(2)). Output: eucledian distance between two feature vectorsĪ. Input: feature vector of query image, feature vector of compared imageī.
extractFeature.m : extract LBP and CM feature of all imagesĮxplanation of Input and Output ParametersĪ. featureVector.m : combine color moment and lbp into single feature vector. Lbp.m : find histogram value of local binary pattern of the input image. Euclid.m : find Euclidian distance between two feature vectors. colorMoment.m : find the color moment based on Stricker Orengo algorithm. However, based on the paper, the accuracy of this method is less than 80% Details of What the Modules Do To run the matlab code, ou can do one of this: press play button above the code, or go to command window and type cbir then enterīecause it uses histogram for LBP, then it is quite robust to image size. For (1) Slow mode, run extractFeature.m then run cbir_rank.m, while for (2) Slow mode, open and run cbir_threshold.m. The threshold for each query image may be varied. That threshold is found after doing some tests on img_test. For cbir_threshold.m, threshold Values and Parameter Values The threshold I set on this program can be found in “th” variable. So, you should be able to track the program logic from the comments available. I already put comment in each different part of the program. So, when it walks to all images in image set, when it find the file similar with query image, it will skip and will not find the feature vector. So, if you want to change the query image, just change this into any image you want. The query image is set by filename variable in cbir_rank.m and cbir_threshold.m. If you want to change the image path, you may change the imgpath variable. In (2) Slow mode, you just run cbir_threshold.m. If you want to change the image path, you must change the path in both extractFeature.m and cbir_rank.m. Threshold Vector Autoregressive Toolbox (last updated on March 19, 2015) Download. For (1), you should run extractFeature.m first, only then you run cbir_rank.m. Report any bugs to gbruneaubankofcanada.ca. In (1) Fast mode, you extract the features from all the images, only then you find the similarity from the features. You can use this program in two modes i.e. Therefore, I avoid using GUI as I am not quite sure that the library of the GUI for each version of matlab is similar. #Matlab vector code for threshold portable
I tried to use as less toolbox as possible so the program is portable to all versions of Matlab. The images are downloaded from Program Design
