How can you identify two black points in an white background image? Can someone help me?
I have got the pixel values for two black points in an image with a white background. That is [x1, y1] and [x2, y2], but now i need to just identify the two black points in the image with a mark or something automatically. Is their a matlab code available to do that, i mean, with the help of the pixel values available,... 8 Jun 2010 22:48

neumann boundary condition in PDETOOL box
Dear Friends, I am trying to solve nonlinear partial differential equation using PDETOOL box. But I am not able to feed Neumann boundary condition. If any one knows how to feed Neumann boundary condition please help me for that. My pde is –div(c*grad(u))+a*u=f c=-1./sqrt(1+ux.^2+uy.^2) a=-1 f=0... 8 Jun 2010 22:48

Defining New Value for a Matrix
Hello, I have an n x m x l matrix. I am trying to create a new matrix (same dimensions) with the same values for the n and m indices, but successively add the values in the 3rd index. For example, where the starting matrix has the values [l1, l2, l3,...] the new matrix should have [l1, l1+l2, l1+l2+l3,...]. Any i... 8 Jun 2010 21:42

measuring torque in simhydraulics
Hi, In the "Power Unit with Fixed-Displacement Pump Demo", the port R of the torque sensor is attached to the angular velocity source and port C to the shaft whose torque is being monitored. My question is that Port C is the reference probe, so why it is connected to the shaft? shouldn't it be connected to the angular... 8 Jun 2010 19:29
