Create bag of words matlab

Oct 31,  · can I use your code for creating a bag of visual words from a SURF feature extracted by 'extractedSURFFeatures' in MATLAB? Actually it creates a multi dimensional feature. and if we use 'extractFeatures' on the out put of the 'extractedSURFFeatures' we can convert in to a jarwinbenadar.coms: The global feature vector extracted from each image (i.e. its bag of visual words) can be seen as a set of numerical attributes. This set of numerical attributes representing the visual characteristics of each image and the corresponding image labels can be used to train classifier. Step 3: Train an Image Classifier With Bag of Visual Words Use the bagOfFeatures encode method to encode each image from the training set. Repeat step 1 for each image in the training set to create the training data. Evaluate the quality of the classifier. Use the imageCategoryClassifier evaluate.
