Abstract

A method for recognizing polluted seawater areas based on high-resolution remote sensing images includes performing automatic sea and land classification on a remote sensing image by using a supervised learning algorithm. The classification result reaches a higher precision level by processized iterative clustering compared to conventional methods. The method further includes combining a chlorophyll-associated normalized difference vegetation index, a brightness-associated normalized difference water shadow index, a segmentation-based image interpretation thought and a human visual saliency-based mechanism in remote sensing interpretation by virtue of a chlorophyll concentration difference of a seawater polluted area and surrounding seawater and a brightness difference of pollutant shadows. The seawater polluted area is extracted by threshold segmentation. An area where the water quality is good and a heavily polluted area are extracted. A pollution transition area is further extracted. The method provides convenience and an accurate reference for prevention and control of marine pollution.

The method makes full use of the discriminant feature to improve detection accuracy of the dim and small object. A symmetric semantic segmentation model and an autoencoder model are used to extract the discriminant feature of an object. A top-down adjustment mechanism is used to fuse an image feature and the discriminant feature of the object. Then an attention mechanism is used to enhance a background to further increase contrast between the object and the background. A multi-scale semantic analysis strategy is introduced, and a pyramid model is used to extract the dim and small object in the video satellite data.

Abstract

The present invention provides a cold-storage instantaneous heat pump water heater (HPWH). The HPWH includes a cold-water tank, a main evaporator, a compressor, and a hot water heat exchanger. In the present invention, heat of a working medium in the cold-water tank is absorbed by the main evaporator, and bathing water is rapidly heated by the hot water heat exchanger (condenser of the heat pump), thereby realizing instant heating with small input electrical power. Cold-water tank replaces the hot water tank of conventional HPWH avoiding energy loss during hot water storage. The working medium in the cold-water tank absorbs heat from the environment, to further improve energy utilization. In addition, there are three energy recovery evaporators to recover the waste heat of bathing.
