  • Publication number: 20210272276
    Abstract: A benign tumor development trend assessment system includes an image outputting device and a server computing device. The image outputting device outputs first/second images captured from the same position in a benign tumor. The server computing device includes an image receiving module, an image pre-processing module, a target extracting module, a feature extracting module and a trend analyzing module. The image receiving module receives the first/second images. The image pre-processing module pre-processes the first/second images to obtain first/second local images. The target extracting module automatically detects and delineates tumor regions from the first/second local images to obtain first/second region of interest (ROI) images. The feature extracting module automatically identifies the first/second ROI images to obtain at least one first/second features. The trend analyzing module analyzes the first/second features to obtain a tumor development trend result.

  • Publication number: 20210262160
    Abstract: The present invention relates to an artificial leather and a method for producing the same. The artificial leather includes a substrate, a thermoplastic ethylene-propylene polymer elastic layer, and a surface layer. The substrate is formed from fibers having a first thermoplastic ethylene-propylene polymer. The surface layer is formed from a second thermoplastic ethylene-propylene polymer. The first thermoplastic ethylene-propylene polymer and the second thermoplastic ethylene-propylene polymer provide the substrate with a specific melting point and the surface layer with a specific melting point, respectively. By the substrate with the specific melting point and the surface layer with the specific melting point, the artificial leather has an excellent post-processability. Therefore, the artificial leather can have the substrate and the surface layer which have the same material, thereby having an excellent recyclability.
