The housing has a device for reading coded information which generates a field projecting through the window towards the outside of the housing, and has a device for visually indicating the result to a user. The visual indication device generates an indication appearing substantially at least on the window, on a portion of the peripheral rim of the window, or on a portion of the housing adjoining laterally the peripheral rim of the window. The housing portion is at least on the left side, right side, or below the window. Additionally, a camera based checkout security system includes at least a checkout security camera and a fixed position reader of coded information. The checkout security camera generates a camera field of view directed towards the window of the fixed position reader of coded information.

Abstract: During a description technique, a local descriptor for an object may be generated by computing a 2-dimensional histogram of pairs of angles between pairs of line segments that are aligned with edge pixels associated with the object. The pairs of line segments belong to a subset of k neighboring or proximate line segments. Moreover, this 2D histogram may represent the relative displacement and the relative orientations of the pairs of line segments in the subset as weights in bins or cells defined by angular quantization values, and the 2D histogram may exclude lengths of the line segments. Subsequently, the generated 2D histogram may be compared to predefined sets of descriptors in a model library that are associated with a set of objects, and the object may be identified as one of the set of objects based on a group of match scores determined in the comparisons.

Abstract: A clutter filter configuration tool for a safety laser scanner. The clutter filter configuration tool may first operate the safety laser scanner in an environment to learn the environmental clutter level and present the same to a user. Subsequent to this “teach-in” phase, the configuration tool may provide a clutter filter selection process which presents the environmental clutter level to the user and allows the user to select a suitable configuration for a clutter filter. The configuration tool may also provide a clutter filter simulation process wherein the clutter filter chosen by the user is verified and a test is performed using the selected clutter filter. The results may be reported on a visualized graph. The configuration tool may also determine a real area to be monitored utilizing a floor projection area and an orientation of the laser scanner.

Abstract: During a description technique (100), a local descriptor for an object (300) is generated (122) by computing a 2-dimensional histogram (600) of pairs of angles (514, 516) between pairs of line segments (510, 512) that are aligned with edge pixels associated with the object (300). The pairs of line segments (510, 512) belong to a subset of k neighboring or proximate line segments (310). Moreover, this 2D histogram (600) may represent the relative displacement and the relative orientations of the pairs of line segments (510, 512) in the subset as weights in bins or cells defined by angular quantization values, and the 2D histogram (600 may exclude lengths of the line segments. Subsequently, the generated 2D histogram (600) may be compared (210) to predefined sets of descriptors in a model library that are associated with a set of objects, and the object may be identified (212) as one of the set of objects based on a group of match scores determined in the comparisons.
