About image processing on fpga

HI i am using matlab 2015b i want to generater VHDL code for sobel edge detection from the simulink model but some blocks for that are not compatible with the HDL code generation.. so what can i do? is it possible to generate VHDL code for the same? and this generated code can be implemented on FPGA(ALTERA)?

Just wanted to confirm that you are trying to find Vision HDL Toolbox and not Computer Vision System Toolbox.

Just use the regular Simulink library list and try to find Vision HDL Toolbox. All blocks in there are compatible for HDL code genration, except for the Frame To Pixels and Pixels to Frame blocks, which are for simulation alone.

ok sir thank you.I want to generate vhdl code for sobel edge detection for an image stored on memory, so i took image from file ,edge detection and video viewer blocks. simulation is working but while generating HDL code i got an error "matrices are not supported at simulink block interfaces" and i am using matlab 2015b. link that you sent me is for 2016b.what should i do? am i going on right way?

You can use the Edge Detection block in Vision HDL Toolbox - that block generates HDL code.

thank you sir. but i tried for that. i am unable to get vhdl code from the model. vision HDL toolbox is not available in 'HDL library browser' that means it is not compatible with the HDL code generation.but in help i found that blockset as compatible. so i am not getting what to do? please help me
