Abstract: A method for judging freshness of cultured fish product based on eye image recognition is provided, which relates to the field of image processing and includes the following steps: obtaining eye area and eye center point of each cultured fish product; obtaining a first data category and a second data category of each gray scale change sequence according to each gray scale change sequence of each eye area; calculating a first mean value and a second mean value of each gray scale change sequence; obtaining the fish eye turbidity of each eye area according to the first mean value and the second mean value; obtaining the fish eye plumpness of each eye area according to the first data category and the second data category; and obtaining the freshness of each cultured fish product according to the fish eye turbidity and fish eye plumpness in each eye area.

Abstract: Disclosed are devices, apparatus, circuitry, components, mechanisms, modules, units, systems, and processes for controlling a power switch of a voltage regulator. A capacitor is coupled to an output of the power switch. Charge delivery circuitry is coupled to the capacitor and configured to provide a charging current to the capacitor. Charge control circuitry can be coupled to the charge delivery circuitry and configured to selectively allow the providing of the charging current to the capacitor.
