NAME
opencv_performance - evaluate the performance of the classifier SYNOPSIS
opencv_performance [options] DESCRIPTION
opencv_performance evaluates the performance of the classifier. It takes a collection of marked up test images, applies the classifier and outputs the performance, i.e. number of found objects, number of missed objects, number of false alarms and other information. When there is no such collection available test samples may be created from single object image by the opencv_createsamples(1) utility. The scheme of test samples creation in this case is similar to training samples In the output, the table should be read: 'Hits' shows the number of correctly found objects 'Missed' shows the number of missed objects (must exist but are not found, also known as false negatives) 'False' shows the number of false alarms (must not exist but are found, also known as false positives) OPTIONS
opencv_performance supports the following options: -data classifier_directory_name The directory, in which the classifier can be found. -info collection_file_name File with test samples description. -maxSizeDiff max_size_difference Determine the size criterion of reference and detected coincidence. The default is 1.500000. -maxPosDiff max_position_difference Determine the position criterion of reference and detected coincidence. The default is 0.300000. -sf scale_factor Scale the detection window in each iteration. The default is 1.200000. -ni Don't save detection result to an image. This could be useful, if collection_file_name contains paths. -nos number_of_stages Number of stages to use. The default is -1 (all stages are used). -rs roc_size The default is 40. -h sample_height The sample height (must have the same value as used during creation). The default is 24. -w sample_width The sample width (must have the same value as used during creation). The default is 24. The same information is shown, if opencv_performance is called without any arguments/options. EXAMPLES
To create training samples from one image applying distortions and show the results: opencv_performance -data trainout -info tests.dat SEE ALSO
opencv_createsamples(1), opencv_haartraing(1) More information and examples can be found in the OpenCV documentation. AUTHORS

NAME
glTexImage2DMultisample - establish the data storage, format, dimensions, and number of samples of a multisample texture's image C SPECIFICATION
void glTexImage2DMultisample(GLenum target, GLsizei samples, GLint internalformat, GLsizei width, GLsizei height, GLboolean fixedsamplelocations); PARAMETERS
target Specifies the target of the operation. target must be GL_TEXTURE_2D_MULTISAMPLE or GL_PROXY_TEXTURE_2D_MULTISAMPLE. samples The number of samples in the multisample texture's image. internalformat The internal format to be used to store the multisample texture's image. internalformat must specify a color-renderable, depth-renderable, or stencil-renderable format. width The width of the multisample texture's image, in texels. height The height of the multisample texture's image, in texels. fixedsamplelocations Specifies whether the image will use identical sample locations and the same number of samples for all texels in the image, and the sample locations will not depend on the internal format or size of the image. DESCRIPTION
glTexImage2DMultisample establishes the data storage, format, dimensions and number of samples of a multisample texture's image. target must be GL_TEXTURE_2D_MULTISAMPLE or GL_PROXY_TEXTURE_2D_MULTISAMPLE. width and height are the dimensions in texels of the texture, and must be in the range zero to GL_MAX_TEXTURE_SIZE - 1. samples specifies the number of samples in the image and must be in the range zero to GL_MAX_SAMPLES - 1. internalformat must be a color-renderable, depth-renderable, or stencil-renderable format. If fixedsamplelocations is GL_TRUE, the image will use identical sample locations and the same number of samples for all texels in the image, and the sample locations will not depend on the internal format or size of the image. When a multisample texture is accessed in a shader, the access takes one vector of integers describing which texel to fetch and an integer corresponding to the sample numbers describing which sample within the texel to fetch. No standard sampling instructions are allowed on the multisample texture targets. NOTES
glTexImage2DMultisample is available only if the GL version is 3.2 or greater. ERRORS
GL_INVALID_OPERATION is generated if internalformat is a depth- or stencil-renderable format and samples is greater than the value of GL_MAX_DEPTH_TEXTURE_SAMPLES. GL_INVALID_OPERATION is generated if internalformat is a color-renderable format and samples is greater than the value of GL_MAX_COLOR_TEXTURE_SAMPLES. GL_INVALID_OPERATION is generated if internalformat is a signed or unsigned integer format and samples is greater than the value of GL_MAX_INTEGER_SAMPLES. GL_INVALID_VALUE is generated if either width or height negative or is greater than GL_MAX_TEXTURE_SIZE. GL_INVALID_VALUE is generated if samples is greater than GL_MAX_SAMPLES. SEE ALSO
