VISUAL ATTENTION APPARATUS AND CONTROL METHOD BASED ON MIND AWARENESS AND DISPLAY APPARATUS USING THE VISUAL ATTENTION APPARATUS
First Claim
1. A visual attention apparatus based on mind awareness, comprising:
- a preprocessor downsampling input images to perform filtering, object segmentation, and context analysis;
a context collection unit collecting context information for context recognition;
a memory storage unit storing context information collected in the context collection unit and favorable impressions of the context information with the objects;
a visual attention processor receiving the filtered images from the preprocessor, the segmented objects, and the context analysis results to collect data from the input images through an extrinsic visual attention model and an intrinsic visual attention model due to command words and the context information and favorable impression stored in the memory storage unit, thereby setting an extrinsic attention region and an intrinsic attention region; and
a visual attention decision unit deciding the attention regions for the extrinsic attention regions and the intrinsic attention regions set in the visual attention processor according to a decision rule.

Abstract
Disclosed are a visual attention apparatus based on mind awareness and an image output apparatus using the same. Exemplary embodiments of the present invention can reduce data throughput by performing object segmentation and context analysis according to downsampling and colors and approximate shapes of input images so as to detect attention regions using extrinsic visual attention and intrinsic visual attention. In addition, the exemplary embodiments of the present invention can detect the attention regions having different viewpoints for each user by detecting the attention regions due to the extrinsic visual attention and the intrinsic visual attention and processing and displaying the attention regions as various regions of interest, thereby increasing the image immersion and the utility of contents.
