When I use the dilation block I don't get any output on the vEnd in the ctrl bus. The pixel input is just a constant with logic 1 for testing. For the inputs hStart, hEND, VStart and VEnd I used counters, which count up to the image border. How do I solve this?

Hi Marc,

The issue may be with frame blanking which the constant input pixel value could be masking to some extent. Take a look at the following documentation for an overview of the expected bus timing, and how to troubleshoot blanking issues:

The recommended minimum horizontal blanking interval is 2×KernelWidth, though there are some additional constraints outlined in the blanking interval configuration documentation. The recommended vertical blanking interval is at least the height of the kernel.

Please create a technical support service request at Contact Us - MATLAB & Simulink (mathworks.com) and attach your model for a proper investigation if you require any more assistance.
