Does simulink have a model that realized the function like imfill ,Nowadays,I'm woking on simulink to build a model that can detect the edge of a cell from the source avi file,an m file implement it mainly used the API called imfill(I,'holes'),First ,I used the Embedded Function to call this API,but I failed ,because it doesn't support this function,How can I realize this funtion?

If you do not plan to generate code from your model, you can use the eml.extrinsic (coder.extrinsic starting in R2011a) directive to declare imfill as an extrinsic function call to be dispatched to MATLAB.

I don't have much experience with the Image Processing Blockset, so I don't know if there is a block equivalent of imfill. If there isn't, then you could indeed implement the function yourself using basic Simulink blocks, or even the Embedded MATLAB functions.

Hi
Im looking for the same thing, a block that applies imfill to a video.
in a function block
function y = fcn(I)
coder.extrinsic('imfill');
y = imfill(I,'holes');
"I" is my video that i want to fill, but get this error
"Function output 'y' cannot be of MATLAB type.
Function 'Filtraje y cuadros/Programing/Lenado' (#55.0.71), line 1, column 1: "function y = fcn(I)"
i'm a beginner in simulink and image processing. What can i do?

You need to pre-declare 'y' so that the block knows what type it should expect, since it can't figure out what type coder.extrinsic functions return.
function y = fcn(I)
coder.extrinsic('imfill');
y = coder.nullcopy(I); %y is the same type as I
y = imfill(I,'holes');
Also, in the future, please create a new question.
