Reference Image Generation for Accurate Region Specification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users face difficulties in specifying an image processing region accurately, especially when no object is present in the intended area, leading to potential faulty detections in applications like dwell detection.
Innovation Solution
An image processing apparatus with an input unit, detection unit, and image determination unit that generates a reference image displaying detected objects, allowing users to easily specify the image processing region by superimposing objects on a background image, and providing methods to protect privacy through graphic representation or silhouettes.

Engineering Contradiction Analysis
1Measurement precision
If the user specifies an image processing region by manually selecting a region in the video image, then the user can define the processing area, but it becomes difficult to specify the region accurately when no object is present in the intended area
Solution Approach 1:
The system performs object detection in advance to generate a reference image showing detected objects and their positions before the user specifies the image processing region. This preliminary action provides visual guidance that helps users accurately specify regions even when no objects are currently present, as they can reference where objects typically appear
Solution Approach 2:
A reference image serves as an intermediary between the raw video image and the user's region specification. This intermediary visual aid displays detected objects and their positions, bridging the gap between automatic detection and manual region selection, thereby improving specification accuracy without complicating the user interface
2Measurement precision
If the user specifies an image processing region based on detected object positions, then detection accuracy improves, but the system complexity increases due to additional detection and reference image generation
Solution Approach 1:
The object detection unit serves multiple functions: it detects objects for the primary image processing task, generates position information for the reference image, and provides spatial context for region specification. This multi-functionality reduces overall system complexity by reusing existing detection capabilities rather than adding separate components
Solution Approach 2:
The reference image is created by copying and overlaying detected object positions and bounding box information onto a copy of the video image. This copying approach allows the system to provide visual guidance without modifying the original video processing pipeline, maintaining simplicity while improving region specification accuracy

AI summary
An image processing apparatus includes an input unit that inputs an image, a detection unit that detects an object from the image input by the input unit, and an image determination unit that determines, based on a result of detection of the object performed by the detection unit on the image input by the input unit a reference image that is to be displayed on a display screen allowing a user to specify an image processing region.
