In the surveillance method, a non-visible light image and a target image are obtained, wherein the target image is generated from a visible light signal captured during a capture period of the non-visible light image.

When an object is detected in the non-visible light image, a second location area of the object in a visible light image is determined according to a first location area of the object in the non-visible light image, such that surveillance of the object is implemented based on the visible light image, wherein the visible light image is an image determined based on the target image.

Abstract: Microparticles include a matrix of an encapsulating material, in which are dispersed particles of a low melting point fat and a bioactive material, such as one or more probiotic bacteria. The microparticles are formed by preparing an emulsion of melted low melting point fat in an aqueous mixture of the encapsulating material, cooling the emulsion below the melting point of the low melting point fat, dispersing the bioactive material in the emulsion and spray drying the emulsion. The particles of solid low melting point fat are believed to protect the bioactive material from heat damage during the spray drying process.
