Various implementations disclosed herein assess the blurriness of portions of images depicting shapes such as codes or text that have known structural elements. This may involve determining whether a portion of an image of a code or text is sufficiently clear (not blurry) to be accurately interpreted. Blur may be assessed based on spatial frequency of statistical analysis. Blur may be assessed using a machine learning model that is trained using target blur metrics determined based on spatial frequency (e.g., analysis of high frequency portions of discrete cosine transforms of image portions) or statistical analysis (e.g., based on corner/edge detection in image portions).

Robust blur estimation for shapes with known structural elements

Various implementations disclosed herein include devices, systems, and methods that provide a visual marker including a plurality of markings arranged in a corresponding plurality of shapes. In some implementations, each marking is formed of a set of sub-markings separated by gaps and arranged according to a respective shape, and the gaps of the plurality of markings are configured to encode data and indicate orientation of the visual marker. In some implementations, the plurality of markings are arranged in a plurality of concentric rings of increasing size. In some implementations, the orientation is encoded in a first set of gaps and data in a second set of gaps of the gaps in the plurality of markings.

Visual marker

One or more computing devices, systems, and/or methods are provided. In an example, an internet resource identification item associated with one or more internet resources may be identified. User activity information associated with a plurality of events may be analyzed to determine a plurality of sets of text associated with the internet resource identification item, wherein each set of text of the plurality of sets of text is associated with an event, of the plurality of events, associated with an internet resource of the one or more internet resources. A plurality of term representations may be determined based upon the plurality of sets of text. A user intention-based representation associated with the internet resource identification item may be generated based upon the plurality of term representations. A content item may be selected for presentation via a client device based upon the user intention-based representation.
