19. A non-transitory computer-readable storage medium storing instructions that, when executed, cause a processing device to perform operations comprising: receiving, by the processing device, digital data representing a page of a publication; identifying, by the processing device, a plurality of potential panels in the page of the publication; determining, by the processing device, a first confidence level a first potential panel of the plurality of potential panels; adding, by the processing device, the first potential panel to a panel view for the publication, wherein the panel view is a digital representation of the publication that allows panel by panel navigation of a set of actual panels, and wherein the first potential panel is automatically added to the set of actual panels in the panel view in view of the first confidence level; determining a second confidence level for a second potential panel of the plurality of potential panels; receiving user input to manually identify the second potential panel as one of the set of actual panels; adding the second potential panel to the panel view for the publication; storing the user input pertaining to at least one of size, shape, location, position or layout of a previously-identified panel to identify additional comic panels as actual comic panels of the publication; determining a third confidence level for a third potential panel using the stored user input; adding the third potential panel to the panel view for the publication, and wherein the third potential panel is automatically added to the set of actual panels in the panel view in view of the third confidence level; receiving, by the processing device, a request for the panel view of the publication; sending, by the processing device, first data enabling a graphical user interface (GUI) to display at least some panel previews of the set of actual panels in a display region, wherein the panel previews are reduced version of the set of actual panels; and sending, by the processing device, second data enabling the GUI to display an enlarged version of a selected one of the panel previews in the same display region.
26. The non-transitory computer-readable storage medium of claim 19 , wherein the operations further comprises: adding a first set of additional panels of the publication that has a confidence level greater than a threshold to the set of actual panels in the panel view; receiving user input for a second set of additional panels of the publication that has a confidence level lower than the threshold; and adding one of the second set of additional panels to the set of actual panels in the panel view in view of the user input.
