# Lukas-Kanade-OpenCL
Lucas-Kanade Algoritm not ended developed for the TFM (Trabajo Fin de Máster) "Máster en nuevas tecnologías electrónicas y fotónicas" UCM
INDICE:
1/Compilación
2/Ejecución
3/Salida
4/Pasos hasta terminar
5/Control errores OpenCL
1/COMPILACION
Para compilar hay que tener instalado el paquete de AMD de Intel o el de NVIDIA que tambien incluye el OpenCL
hay que saber en que directorio esta el CL.h y la libreria libOpenCL.so. Se compila con gcc
gcc nombrearchivo.c -std=c99 -I/opt/direcciondelincludeCL.h -L/opt/direcciondelalibrerialibOpen -lOpenCL
Ejemplo compilación:
gcc LK_1.c -Wall -std=c99 -I/opt_speedy/AMDAPP/include -L/opt_speedy/AMDAPP/lib/x86_64 -lOpenCL
2/EJECUCION
Para la ejecución hace falta un fichero de video binario conocer las dimensiones de cada frame el número de frames e indicar el
tamaño del bloque y del filtro.
Ejecutar a.out:
./a.out ./estimulos/divergingtree_150x150_40frs.bin 150 150 40 5 10
3/SALIDA
El código genera dos ficheros U.raw V.raw con las velocidades de cada pixel para el frame. Visualizar con el código showUV.m desde Matlab
4/PASOS HASTA TERMINAR
Falta generar dos ficheros de velocidades pero con todos los frames
Ajustar el kernel para que no de erores en el tratamiento de los bordes
5/LISTA ERRORES OPENCLL:

CL_IMAGE_FORMAT_NOT_SUPPORTED -10 the image format is not supported.
CL_BUILD_PROGRAM_FAILURE -11 program build error for given device, Use clGetProgramBuildInfo API call to get the build log of the kernel compilation.

CL_COMPILE_PROGRAM_FAILURE -15 failed to compile the program source. Error occurs if clCompileProgram does not return until the compile has completed
CL_LINKER_NOT_AVAILABLE -16 Linker unavailable
CL_LINK_PROGRAM_FAILURE -17 failed to link the compiled binaries and perhaps libraries

CL_INVALID_DEVICE -33 device/s specified are not valid
CL_INVALID_CONTEXT -34 the given context is invalid OpenCL context, or the context associated with certain parameters are not the same
CL_INVALID_QUEUE_PROPERTIES -35 specified properties are valid but are not supported by the device, its returned by clCreateCommandQueue / clSetCommandQueueProperty
