Abstract: Aspects of the disclosure relate to facilitating review of labels. For instance, a first type of label for a first set of labels and a second type of label for a second set of labels may be received. The first set of labels may be generated by a first labeling source and may classify one or more objects captured by a sensor of a vehicle. The second set of labels may be generated by a second labeling source different from the first labeling source and may classify the one or more objects. A search is conducted for objects associated with both the first type of labels for the first set of labels and the second type of label for the second set of labels in order to identify search results. The histograms may be generated from the search results and histograms may be provided for display to a human operator.

Abstract: Methods, systems and computer readable media for visualizing a collection of graphs, wherein each of the graphs may be aligned along one axis of a visualization. All graphs are aligned with respect to the one axis. At least one metadata value per graph is aligned in a first form of representation with each graph, respectively. Visualization of the graphs are compressed in a direction along a second axis perpendicular to the first axis, and visualizations of the metadata values aligned with the compressed visualizations of the graphs are represented graphically.

Abstract: A method is provided for displaying a page formed of discrete elements, such as a Web page, on different computing devices. The method converts the page into a semantic thumbnail, which preserves the overall appearance of the page and displays readable text segments that enable a user to identify main areas of the page. The semantic thumbnail is adaptable to different screen sizes and target font sizes. The method enlarges unreadable text segments in a miniature version of the page. The method also trims the enlarged text segments to fit the width of the semantic thumbnail by summarizing or cropping text in the enlarged text segments.
