| DataManager | Manages Texture Memory on Graphics Card |
| FragmentProgram | Represents a Cg Fragment Shader for GPGPU |
| FramebufferObject | |
| FrameUnit | Frame Unit stores a few texture blocks that make up the Pyramid for a single video frame. It contains 2 blocks for each pyramid level - main and auxi Buffers |
| GaussianFilter | Represents a filter that does Gaussian Filtering Encapsulates the Gaussian Filtering Operation using GPGPU with Cg Shaders |
| GpuKLT_Feature | Object represents a single KLT Feature This Object stores information associated with a KLT Feature |
| GpuKLT_FeatureList | Object represents a List of KLT Features This Object stores information regarding a collection of Features. For eg. all the GpuKLT Features found in an image |
| GpuVis | Object performs different operations on the GPU. It requires a single initialization call, application needs to interface with this object by passing in image objects This class extracts KLT features and returns them in KLT feature lists |
| GpuVIS_Image | Object represents the Image data structure recognized by the GPU VIS library |
| GpuVis_Options | Object contains options and global setting for the GPU VIS computation |
| ImgFilter | Represents a Local Filter Operation on an Image Stream in GPGPU framework |
