Now, if we increase height of each rectangle by 1 pixel after changing width of each rectangle from 1 pixel to 24 pixels until height of each rectangle becomes 24 pixels, then Don’t be mislead by this, it means than after the long training process your detection algorithm should be very fast and it only needs to check few features (just the ones selected during training). Haar-like features prefer fixed positions for feauters, which explains these results.

We found one dictionary with English definitions that includes the word haar-like feature: Click on the first link on a line below to go directly to a page where haar-like feature is defined. General (1 matching dictionary) For example consider one of the original feature which has two rectangles adjacent to each other. Let us consider size of each rectangle is 1 pixel. Initially if one rectangle is present on (0,0) of 24*24 image then it is considered as one feature & now if you move it horizontally by one pixel( to (1,0) ) then it is considered as second feature as its position is changed to (1,0). In this way u can move it horizontally upto (22,0) generating 23 features. Similarly, if you move along vertical axis from (0,0) up to (0,23) then u can generate 24 features. Now if you move on image covering every position (for example (1,1),(1,2).....(22,23) ) then u can generate 24*23=552 features.

  4. bool isStageTrained = tempStage->train( (CvFeatureEvaluator*)featureEvaluator, curNumSamples, _precalcValBufSize, _precalcIdxBufSize, *((CvCascadeBoostParams*)stageParams) ); Every weak classifier is constructed by checking each feature and chosing the one that yields the best result at that point (in case of a decision tree the process is similar). After this choice, the weights of samples are changed accordingly, so that at the next round a different feature, from all the feature set again, will be selected. A single feature evalution is computationally cheap, but multiplied by numFeatures can be demanding. The whole training of a cascade can take weeks, but the bottleneck is not the feature evaluation process, it is the negative sample gathering at latest stages.

A simple way to find out which region is lighter or darker is to sum up the pixel values of both regions and comparing them.

This can be accomplished using Haar-like features. add a comment  |  0 It seems to me that there is a little bit of confusion here. Even the accepted answer seems not correct to me (maybe I haven’t got it well). The original Viola-Jones algorithm, the main later improvements of it as the Lienhart-Maydt algorithm, and the Opencv implementation, all of them evaluate each and every feature of the feature set in turn. You can check the source code of Opencv (and whatever implementation you prefer). At the end of function void CvHaarEvaluator::generateFeatures() you have numFeatures, which is just 162,336 for BASIC mode and size 24x24. And all of them are checked in turn, when all the feature set is provided in the form of featureEvaluator (source):in a standard 24x24 pixel sub-window, there are a total of M= 162,336 possible features, and it would be prohibitively expensive to evaluate them all when testing an image.

Now, if we consider width of each rectangle is 1 pixel and height as 2 pixel. Initially if one rectangle is present on (0,0) and is moved along horizontal axis up to (23,0) then we can have 23 features as its width is 1 pixel, as its height is 2 pixels if we move along vertical axis from (0,0) to (0,22) then we can have 23 features. Thus if we move so as to cover every position on image then we can have 23*23=529 features. Like4Like is helping Facebook users to get more likes on pages, posts, and videos.

Is there any guideline about the initial number of features? You start by manually choosing a feature type (e.g. Rectangle A). This gives you a mask with which you can train your weak classifiers. In order to avoid moving the mask pixel by pixel and retraining (which would take huge amounts of time and not any better accuracy), you can specify how much the feature moves in x and y direction per trained weak classifier. The size of your jumps depend on your data size. The goal is to have the mask be able to move in and out of the detected object. The size of the feature can also be variable.
