The invention discloses a method based on monocular vision for detecting and roughly positioning the edge of a road, and relates to the field of machine vision and intelligent control. Aiming at a continuous road with different edge characteristics, two road edge detection methods are supplied and suitable for semistructured and nonstructured roads and can be applied to vision navigation and intelligent control over a robot. The invention provides a method for detecting the edge of the road based on colors and a method for detecting the edge of the road based on threshold value partitioning. On the basis of the obtained edge of the road, an image is subjected to inverted perspective projection transformation, so that a front view is transformed into a top view; and according to a linear corresponding relation between a pixel and an actual distance in the image, a perpendicular distance from the current position of the robot to the edge of the road and a course angle of the robot can be calculated. The method is easy to implement, high in anti-interference performance, high in instantaneity and suitable for the semistructured and nonstructured roads.

A method for adapting a hearing device (6, 7) to the hearing needs and preferences of an individual (U) is presented, wherein sound processing in said hearing device (6, 7) is programmable by means of adjustable parameters. The method comprises the steps of

• a) presenting at least one auditory test signal (1a) to said individual (U);
• b) capturing at least one image (2a) of at least a portion of said individual's body;
• c) analyzing said at least one image (2a);
• d) deducing from said image analysis whether or not said individual (U) has shown a reaction upon said presenting said at least one auditory test signal (1a) and, if yes, which reaction said individual (U) has shown;
• e) determining, in dependence of said at least one auditory test signal (1a) and of said reaction or lack of reaction, a setting for at least one of said adjustable parameters.

The invention discloses a preparation method of a magnetic adsorptive material and application thereof. The preparation method comprises the following steps: performing acid pickling and alkaline wash on granular active carbon GAC so as to obtain the pretreated GAC; mixing with Co(NO3)2.6H2O, Fe(NO3)2.9H2O and AgNO3, adding deionized water to be dissolved and stirred, carrying out hydrothermal reaction on the obtained mixture in a reaction kettle, filtering the reacted product, washing with deionized water and ethanol until any color does not exist, performing drying and high-temperature calcining on the obtained colorless product, and finally obtaining granular active carbon Ag-CoFe2O4-GAC loaded with silver cobalt ferric oxides. The modified GAC has improved adsorptive property and also has magnetic property, heavy metals are removed from a water body by virtue of adsorption and magnetic separation when wastewater containing heavy metals is treated, the modified GAC serves as a novel magnetic adsorptive material, and the effect of treating the heavy metals in the wastewater is obviously improved.
