Abstract: Disclosed herein are systems, methods, and devices for using adaptive learning to identify objects. An object-identifying device performs a first object identification based on one or more features of a first modality of an object retrieved from an image frame including the object and a first database including first modality identification features. A second object identification is performed based on one or more features of a second modality of the object retrieved from the image frame and a second database including second modality identification features. The second database is updated by adaptively learning a new second modality identification feature according to a first identification result of the first object identification. The second object identification is trained with the updated second database and determines a final identification result by integrating a first identification result of the first object identification and a second identification result of the second object identification.

Abstract: A system for video segmentation may include a neural network and a memory including multi-range arrays. The multi-range arrays may store feature map arrays including different number of feature maps. The system may generate a feature map from a frame in a video at a time and store the feature map in the memory.

The system uses the feature map array to determine whether the frame falls into a segment of the video. The system may generate a new feature map later from another frame and include the new feature map in a new feature map array that also includes the first feature map. The system uses the new feature map array to determine whether the new frame falls into a segment.

Abstract: A Hydrophilic-Lipophilic Deviation theory-based method is provided to prepare representative degassed oil with equivalent minimum miscible pressure to live oil. The method can reduce the number of trial and error type experiments during the representative degassed oil preparation process by measuring the MMP and EACN for dead and live oil. The representative degassed oil formulation could be easily predicted after determining the required MMP and EACN values. The prepared oil can reflect the key mechanism of multiple contact miscible mechanism in the process of gas flooding more accurately. It allows experiments that are inconvenient to use live oil to consider the mechanism of multiple contact miscibility easily.
