Abstract: A method for detecting an object containing recycled plastic materials by qualitative and semi-quantitative detections is revealed, in which observing a yellowing condition of the object using a first light source, and illuminating the object using a second light source for observing a defect amount on the surface image of the object. When a yellowing index of the object is smaller than a standard yellowing index as well as a second defect condition is greater than a first defect condition, and an activation energy value of the object from a thermogravimetric analyzer is smaller than a standard activation energy value, the object does contain recycled plastic materials. Since the spectrums of recycled PET and native PET are different, the object contains recycled PET and the proportion of the recycled PET are determined according to the spectrums of fluorescent spectrum analysis and the difference ratio between the spectrums respectively.

Abstract: In various examples, systems and method are provided for generation of ground truth gaze data for training in-cabin monitoring systems and applications. A gaze target projector mounted to a known position inside a cabin may be used to project a gaze target onto an interior surface of the cabin. Because a beam of light may be used to produce the projected gaze target, the projected gaze target may be displayed at a projection point on the surface of the cabin interior, even if the surface at the projection point is curved, small, or an irregular shape. Three-dimensional coordinates of a projected gaze target in the cabin coordinate system may be determined and used to label image data that is captured as a projected gaze target is selectively projected onto an interior surface of the cabin and a test occupant's gaze is directed at the projected gaze target.

A loss calculation module calculates supervised loss using actual labels and computes reverse consistency loss between the prediction results.

Abstract: An image processing method for a video processor includes receiving a first input frame at a first time instant, receiving a second input frame at a second time instant, and creating an interpolated frame. When no input frame is received at a third time instant, the interpolated frame is generated using extrapolation according to the first and second input frames. When a third input frame is received at the third time instant, the interpolated frame is generated using interpolation according to the second and third input frames. The video playback smoothness can be improved by dynamically switching between extrapolation and interpolation.

Abstract: The present disclosure relates to an automatic scalp sebum classification system and a method for automatic classification of scalp sebum. A high-resolution image of a part of the scalp is captured and divided into non-overlapping blocks. Random rotation and position swapping of the blocks are performed for data augmentation and privacy preservation. Each block is then converted into a one-dimensional vector, to which positional information is added through learnable embedding vectors. The vectors are input into a visual transformation model that outputs a sebum classification label. The automatic scalp sebum classification system and method for automatic classification of scalp sebum offer advantages in speed, accuracy, and privacy preservation over traditional and other AI-based methods.
