## How to obtain the common numbers between this 2 sequences?

Any odd number can be written as: $$n = \left(\frac{n + 1}{2}\right)^2 – \left(\frac{n – 1}{2}\right)^2$$ If I take: $$a^2=\left(\frac{n + 1}{2}\right)^2$$ and: $$b^2=\left(\frac{n – 1}{2}\right)^2$$ If I subtract $1$ from $a$ or $b$, then $3$ to the previous, then $5$ and so on, I will always obtain $n$ […]

I have an ultrasound image and the coordenates (array of x and y points) of the tumour of each image. How can I make a contour around the tumour with those known coordenates using “cv.drawContours()”? I wish to delete all the information around the tumour and stay only with the tumour image/information. temp=np.array([[284., 60.],[276., 59.],[269., […]
