struct | Param |
Public Member Functions | |
ColorHistShader (Param *param=NULL) | |
Constructor. | |
void | copyHistoFromGPU (opentl::core::cvdata::ColourHist2d &MDestination) |
Copy back the histogram from GPU. | |
virtual void | execute () |
Shader execution (overrides the base class method). | |
opentl::cvprocess::GlFbo * | getCurrentFbo () |
Get the current FBO (if we want to upload textures from outside, we need to bind to the current FBO!) TODO: This is hacking the class... make it with another function, for uploading/downloading the textures from outside! | |
int | getNBlocks () |
Return actual number of sub-histograms. | |
Param & | params () |
Get/Set parameters for this class. | |
virtual void | prepareDisplayList () |
Fixed display list for computing the histogram in parallel, by dividing the image into blocks of fixed size. | |
virtual | ~ColorHistShader () |
Destructor. |
The histogram can be used for color-based matching NOTE: Derived class from GpuStdShaders.
opentl::cvprocess::ColorHistShader::ColorHistShader | ( | Param * | param = NULL |
) |
Constructor.
param | Structure of parameters for this class |
virtual opentl::cvprocess::ColorHistShader::~ColorHistShader | ( | ) | [virtual] |
Destructor.
void opentl::cvprocess::ColorHistShader::copyHistoFromGPU | ( | opentl::core::cvdata::ColourHist2d & | MDestination | ) |
Copy back the histogram from GPU.
MDestination | Destination histogram (the source is the GPU texture mColourHistoTexture) |
virtual void opentl::cvprocess::ColorHistShader::execute | ( | ) | [virtual] |
Shader execution (overrides the base class method).
Reimplemented from opentl::cvprocess::GpuStdShaders.
opentl::cvprocess::GlFbo* opentl::cvprocess::ColorHistShader::getCurrentFbo | ( | ) | [inline] |
Get the current FBO (if we want to upload textures from outside, we need to bind to the current FBO!) TODO: This is hacking the class... make it with another function, for uploading/downloading the textures from outside!
int opentl::cvprocess::ColorHistShader::getNBlocks | ( | ) | [inline] |
