An image processing device includes a processing circuit, a detection circuit, a setting circuit, and a decision circuit. The processing circuit obtains, from image data of a document read by a reading device, a value relating to a difference between pixel values of adjacent pixels in a direction from a background portion to a document portion in the image data. The detection circuit searches for a pixel in the direction and detects an edge, which indicates a boundary between the background portion and the document portion, based on the value relating to the difference. The setting circuit sets the detected edge as a first edge or a second edge. The decision circuit decides the second edge as a document edge of the document.

Abrégé

A cognitive agent system provides a centralized capability for users to configure and deploy cognitive agents across multiple heterogeneous vendor platforms. The cognitive agent system provides a design environment that allows users to define skills, as well as a new conversation construct that supports more complex interactions with users. The cognitive agent system also includes a deployment environment that allows users to register users and cognitive agents, deploy skills and conversations, and monitor the activity of cognitive agents across multiple vendor platforms. These users may use the cognitive agent system to define skills and conversations once and then deploy the skills and conversations to multiple service endpoints across different vendor platforms. In addition, the cognitive agent system allows user to directly manage cognitive agents that are not specific to any particular vendor.
