What are the features you're measuring and going to pass to kmeans()?

i have divided the image into blocks of 20*20, and i wanna calculate the size of the object in each block. After that, i pass the size and cell(blocks) to K means.

  1. Decide first your features
  2. Prepare features from your extracted blob/blob size data, and
  3. You need to make table/matrix of the features including the class name/label.
  • Now pass your feature matrix/table to one of the classification methods. The procedure will generate one structure file from which you can predict un-labled/unknown data.

If Area of the blob is your feature:
  • Calculate area of the blobs and prepare matrix/table. Follow above steps.
