When compiling the code I received the error

CMake Error at CMakeLists.txt:39 (check_function_exists):
  Unknown CMake command "check_function_exists".

I added

include(CheckFunctionExists)

below the project name and this fixed the issue.

Is there any paper related to this work ?
I use your codes in my paper and want to cite your paper.
Thanks.

Hi, is the slic_zero version of the algorithm available, and if not, is that due to some cuda limitations?
Thanks!

Maybe it is not a good idea to set CUDA_COMPUTE_CAPABILITY manually, which may lead to some unexpected errors.

I change the code in CMake from

### CUDA CHECK 
find_package(CUDA REQUIRED)
set(CUDA_COMPUTE_CAPABILITY "52")
set(CUDA_GENERATE_CODE "arch=compute_${CUDA_COMPUTE_CAPABILITY},code=sm_${CUDA_COMPUTE_CAPABILITY}" CACHE STRING "Which GPU architectures to generate code for (each arch/code pair will be passed as --generate-code option to nvcc, separate multiple pairs by ;)")
set(CUDA_NVCC_FLAGS ${CUDA_NVCC_FLAGS} -arch compute_${CUDA_COMPUTE_CAPABILITY})

to

find_package(CUDA REQUIRED)

I tested this code and works.

the opencv SLIC function returns labels running from 0 to the number of labels, which is extremely convenient for processing the superpixels after the fact. This version just seems to use arbitrary values for each label. Also it lacks a numSuperPixels() function like the opencv version has. might make a contribution at some point to fix this.
