Abstract: Disclosed herein is a method for assisting in Autism Spectrum Disorder (ASD) diagnosis. The method includes transmitting social-interaction-inducing content, receiving input images containing a response of an assessment subject to the social-interaction-inducing content, receiving an ASD diagnosis result for a preset number of input images, among the received input images, and outputting a diagnostic assistive result for the received input images using ASD diagnosis input for the preset number of input images and a pretrained global ASD diagnosis model.

Abstract: Disclosed herein is a method for supporting an attention test based on an attention map and an attention movement map. The method includes generating a score distribution for each segment area of frames satisfying preset conditions, among frames of video content (video) that is produced in advance so as to be suitable for the purpose of a test, generating an attention map corresponding to the frames based on the distribution of the gaze point of a subject, generating an attention movement map corresponding to the frames based on information about movement of the gaze point of the subject, and calculating the attention of the subject using the score distribution for each segment area, the attention map, and the attention movement map.

Abstract: Disclosed herein are a deep neural network (DNN) learning method for generalizing appearance-based gaze estimation and an apparatus for the same. The deep neural network (DNN) learning method includes creating multiple augmented images based on an original image, inputting the multiple augmented images to a DNN to output a gaze estimation value, calculating a total loss between a gaze ground truth of the original image and the gaze estimation value through gaze consistency regularization (GCR) using a spherical gaze distance (SGD), and updating parameters of the DNN by backpropagation of the total loss.

Abstract: Disclosed is a computing device, which includes a processor, a camera that captures RGB image data, a memory that stores image data including the RGB image data, and a pupil detection device that detects a pupil from the RGB image data stored in the memory in response to a request of the processor. The pupil detection device includes an image converter that receives the RGB image data, detects first eye area data including eye area information from the received RGB image data, and converts the first eye area data into second eye area data having IR (InfraRed) image characteristics by using a deep neural network, a pupil candidate detector that detects pupil candidate data from the second eye area data, and a pupil boundary detector that detects pupil boundary data from the pupil candidate data.

Abstract: Disclosed herein are an apparatus and method for monitoring a user based on multi-view face images. The apparatus includes memory in which at least one program is recorded and a processor for executing the program. The program may include a face detection unit for extracting face area images from respective user images captured from two or more different viewpoints, a down-conversion unit for generating at least one attribute-specific 2D image by mapping information about at least one attribute in the 3D space of the face area images onto a 2D UV space, and an analysis unit for generating user monitoring information by analyzing the at least one attribute-specific 2D image.
