For example, an image classification algorithm can tell if an image contains a cat or not. To achieve this, we will create a classifier by importing the svm as we imported datasets from sklearn: >>> from sklearn import svm >>> classify = svm.SVC(gamma=0.001) The main purpose of this is to slice or separate the images and labels. To summarize, Support Vector Machines are very powerful classification models that aim to find a maximal margin of separation between classes. I have problem with classification using SVM. You'll need a huge amount of non-digit images to make it work, and also it's recommendable to use strategies as the selection of hard negatives: negative samples classified as "false positives" after the first training stage, which are used to re-train the classifier. Object tracking (in real-time), and a whole lot more.This got me thinking – what can we do if there are multiple object categories in an image? The world has been changed, human is being replaced with machine.
