Abstract: Techniques described herein provide for automated near-duplicate detection for new text documents given text documents that were previously processed using automated near-duplicate detection for text documents. In one example, a system can receive new documents and documents that were previously processed using a predefined processing technique for automated near-duplicate detection. The system can process the new documents and cluster the new documents into multiple predefined clusters previously identified using the predefined processing technique. For each predefined cluster including at least one new document, the system can generate document groups by determining similarity scores using the predefined processing technique as applied to the documents in the predefined clusters. The system can identify a representative document for each document group and generate an output data structure including the document groups and the representative document for each group.

Abstract: Techniques described herein provide for text string comparison for documents identified using automated near-duplicate detection. In one example, a system can receive a pair of documents. The system can extract text strings from the documents. The system can normalize the extracted text strings using a predefined normalization scheme. The system can identify boilerplate text segments in the normalized text strings. The system can remove the boilerplate text segments from the normalized text strings to generate filtered text strings. The system can divide the filtered text strings by identifying section indicators. The system can, for each section, generate groupings of text strings and determine a similarity score between each pair of corresponding groupings to identify matching groupings of text strings. The system can generate an output for display showing the visual indications of the matched groupings of text strings.

Abstract: In a method for collision event determination, a first estimated trajectory that a target object is expected to follow during a next movement period is obtained. A second estimated trajectory that a collision object is expected to follow during the next movement period is obtained. A spatial positional relationship between the first estimated trajectory and the second estimated trajectory is determined to satisfy a reference collision condition. Based on the determination that the spatial positional relationship between the first estimated trajectory and the second estimated trajectory satisfies the reference collision condition, a candidate collision space that indicates a space through which the target object is not allowed to move is determined. A collision event is determined to occur between the target object and the collision object when a plurality of candidate object positions on the first estimated trajectory include a target object position in the candidate collision space.

Abstract: A low-complexity panoramic video coding method considering distortion temporal propagation is provided. By analyzing the inter-frame reference relationships under the random access coding structure and establishing the corresponding distortion propagation chain, the method utilizes distortion impact factors of coding units to adjust encoding parameters, thereby optimizing the encoding process. Furthermore, the method addresses the issue of oversampling arising from the varying geometric deformations in different latitude regions during the projection of spherical images in panoramic videos. This is achieved by adjusting coding parameters based on the ratio of area changes at different latitudes. The proposed approach significantly enhances coding performance.

In one example, a system can cluster documents into a set of clusters based on character frequencies associated with the documents.

Next, the system can convert the filtered group of documents into matrix representations. The system can generate second similarity scores for every pair of matrix representations. The system can then identify documents, from among the filtered group of documents, associated with second similarity scores that meet or exceed a second predefined similarity threshold. The identified documents can be duplicate or near-duplicate text documents.
