How to use DBSCAN algorithm for a list of points in python

Asked 2017-Nov-30 at 06:32

I am new to image processing and python coding. I have detected a number of features in an image and have their respective pixel locations placed in a list format.

Your data is a list of tuple. There is nothing in this structure that prevents you from doing crazy things with that, such as having different lengths in there. Plus, this is a very slow and memory inefficient way of keeping the data because everything is boxed as a Python object.

Just call data = numpy.array(data) to convert your data into an efficient multidimensional numeric array. This array will then have a shape.

looks like static background so I would:

on Each frame A

blur A a bit to remove noise
substract/threshold last frame A0 from A

so dA=A-A0 and create ROI by |dA|>threshold. This mask will contain areas where ants where and are now.
set last frame

so A0=A

To recognize which part of ROI is the old and actual ant position just check correspondent pixel in A for black ...

I do not use Python nor OpenCV so I am not confident to provide any code ...

Instead of A0 you can also use the background image (without ants) or integrated/averaged image over time...

OpenCV-Python image processing, Type error

Asked 2017-Apr-26 at 03:47

I am using the below mentioned code to track brown coloured magnetic beads. The line cv2.circle(frame, center, 5 ,(0,0,255),-1) is giving a Type error. Can anyone provide insight on this?

ANSWER

Answered 2017-Apr-26 at 03:47

Type error occurs when the expected type of data is not fed. Any other type other than the expected type leads to this error.

You have to modify your line from:

center = (int(M["m10"]/M["m00"]),(M["m01"]/M["m00"]))

to:

center = (int(M["m10"]/M["m00"]), int(M["m01"]/M["m00"]))

You did not include type int to the second coordinate of the center, hence you have been receiving this error all the while.
