This approach is based on the application of a colour based object detection technique, a method for HSV, and the key points matching technique.


We propose a novel and robust color object detection and localization algorithm. Without a priori information about the number of objects, our method can detect all the objects with similar color feature in template. An SIFT and key points matching algorithm is used to find the object candidate regions. The weighted histogram intersection is used to verify the presence of objects. With the color feature in template, our method can detect and locate the objects accurately, get the number of objects, estimate their scales and orientations. Our experimental results on outdoor images obtained under different environments verify the effectiveness of our algorithm


Existing system is based on the color joint probability function, in this it will look for the centroid of the colors and color edge co-occurrence histogram, so that the accuracy of this system will less.


Here we are going to use the HSV for the color conversion, scale invariant feature transform for the feature extraction in the image and based on the key points matching the color object is identified.


colour based object detection using python opencv


  • Better accuracy in segmentation under various illuminations
  • Less time consuming process
  • It is less sensitive to background noise


  • People counting
  • Vehicle detection
  • Manufacturing industry applications
  • Tracking objects


  • Python
  • Opencv
  • Numpy


  • Thus the color based object is detected by this proposed system. And in future the object can be tracked by the same method.
