Abstract
In some examples, a computing device can include a processor resource and a non-transitory memory resource storing machine-readable instructions stored thereon that, when executed, cause the processor resource to: identify a plurality of regions within a captured document, determine a quantity of vertical transitions and horizontal transitions within the plurality of regions, and select an output resolution for the plurality of regions based on the quantity of vertical transitions and horizontal transitions within the plurality of regions.
Claims15
A computing device, comprising:
- a processor resource;
- and
- a non-transitory memory resource storing machine-readable instructions stored thereon that, when executed, cause the processor resource to:
- identify a plurality of regions within a captured document;
- determine a quantity of vertical transitions and horizontal transitions within the plurality of regions;
- and
- select an output resolution for the plurality of regions based on the quantity of vertical transitions and horizontal transitions within the plurality of regions.
A non-transitory memory resource storing machine-readable instructions stored thereon that, when executed, cause a processor resource to:
- identify a plurality of regions within a captured document, wherein one of the plurality of regions includes a symbol region;
- generate a plurality of resolution tiers for the symbol region;
- assign a classification to the symbol region for the plurality of resolution tiers, wherein the classification is one of a readable classification and a non-readable classification;
- and
- select an output resolution for the captured document based on the classification of the symbol region for the plurality of resolution tiers.
A scanning device, comprising:
- an image captured device;
- and
- a processor resource to:
- receive image data of a document from the image capture device;
- identify an image portion from the image data of the document;
- identify a plurality of regions within the image portion;
- determine a quantity of vertical transitions and horizontal transitions within the plurality of regions;
- determine an edge density of the plurality of regions based on the quantity of vertical transitions and horizontal transitions within the plurality of regions;
- select an output resolution for the image portion based on the edge density;
- and
- perform post-processing on the captured image using the selected output resolution for the document.
