Feed: CronJ. Author: Pavan Kalyan; As we have discussed HOG: Calculating Image Features in detail in my previous blog. We understood the basic concept behind HOG and all the steps of implementation of HOG in detail. Today we will discuss Feature Matching using HOG.  After the implementation of all the steps of HOG, we get a vector which is basically a feature vector of that image. The total number of features obtained from the HOG are quite large in number. Like in the previous blog, we obtained the HOG feature vector of size 3780, which is a quite big number ... Read More

Understanding Javascript Variable Scope and Hoisting Well, we know how the scopes of the programming language work, but it’s not the same for all programming languages. In javascript, the variable scope and its hoisting are quite different. Let’s take an example – var car = “Mercedes” // variable is defined in the global scope function  car_name () { // function car = “BMW”; // this is a local scope but the variable car is global variable var car ...
