load_image()

MatrixD dl::utils::ImageLoader::load_image ( const std::string &  filename, size_t  target_width = 0, size_t  target_height = 0  )

static

Load a single image file.

Parameters

filename	Path to the image file
target_width	Target width for resizing (0 = no resize)
target_height	Target height for resizing (0 = no resize)

Returns

Matrix containing normalized pixel values [0,1]

Note

Images are converted to grayscale and normalized

std::vector< MatrixD > dl::utils::ImageLoader::load_images_from_directory ( const std::string &  directory_path, size_t  target_width = 0, size_t  target_height = 0  )

static

Load all images from a directory.

Parameters

directory_path	Path to directory containing images
target_width	Target width for resizing (0 = no resize)
target_height	Target height for resizing (0 = no resize)

Returns
