Both classification problems and object recognition problems need to be labeled.Ĭompared with other tools, the wizard label assistant is very simple and convenient. Introduction to the Wizard Marker Assistant: ThereĪre many situations in the field of artificial intelligence that require marked data, such as pictures, videos, and text. Otherwise, it leave two annotations for the object.Before this, the pictures need to be filtered to improve efficiencyġ. different annotations for one object, and if "Vote to decide annotaions" is active, File Sorter decides one most frequently annotatted class for the object. If the "overlaped" annotations have conflicts, e.g. The annotations evaluated as "overlaps" will be merge as one annotation. If multiple annotations indicated by rectangles are found, File Sorter evaluates whether percentages of overlaping areas covered by the annotation rectangles exceed the value specified at "Percentage of overlapped area". In that case, "Percentage of overlapped area" need to be specified.įile Sorter algorithm first generate the original iamge from the sliced images with location information stored in an iamge coordinate file and then put all annotation information over the image. You can select one best annotation for the object by activating the radio button "Vote to decide annotations". In the situation 1, a same object can be annotated as different classes in separate files of sliced images with overlaps each other. single (non-sliced) images annotatted via an image classification model.single (non-sliced) images annotatted via an objecte detection model.sliced images annotatted via an objecte detection model.The directory containing the input image files to be sorted should be specified as "Input directory", while "Output directory" indicates the directory under which directories will be created to sort the input image files.įile Sorter accepts three situations which input images are: File Sorterįile Sorter sorts image files into separate directories based on annotations given via RectLabel.īased on the annotation information in a json file generated by RectLabel, this function create directories and put image files. The output directory includes an image coordinate file which shows original locations of sliced images in the input image. If the directory specified at "Output directory" does not exist, it will be created. The next slice of the image will starts at the 251th pixel from the left end of the input image as specified at "Set step width of image slicing".Īfter the slicing hit at the right end of the input image, the next slice starts from the left end again but at the 251the pixel from the top as specified at "Set step height of image slicing".Īll of the sliced images will be created in the directory specified as "Output directory". If you set values as shown the image above, the first image of slices starts from the top-left corner of the input image with 500 x 500 px. Similarly, "step width of image slicing" and "step height of image slicing" indicate how much a sliced image overlaps along the horizontal axis and the vertical axis with the next image. The width and height of sliced images can be specified in px. Please specify an input image via clicking the "Input image file" button. Image Slicer cuts a large image into pieces with a specified size and overlapps between images. "File sorter" enable you to classify image files in an input folder into separate folders based on annotation information generated via RectLabel. When you execute ImageSorter, you will see a window like shown below.Ĭlick the "Image Slicer" tab to slice a image into pieses.
