Provided are a method and an apparatus for detecting a thickness of paper, and a storage medium. The method includes: acquiring a first thickness image of a target paper; extracting at least one first thickness feature and at least one second thickness feature from the first thickness image in the first thickness image; performing average processing on gray values of multiple pixel points in the at least one first thickness feature to acquire a first gray value, and the average processing is performed on gray values of the multiple pixel points in the at least one second thickness feature to acquire a second gray value; when the first gray value is smaller than the second gray value of multiple pixel points in at least one second thickness feature, determining that a thickness of a region, corresponding to the at least one second thickness feature, on the target paper has changed.

Provided are a detection method, a detection apparatus and a detection process. The detection method includes: using a sensor for idle scanning to obtain a first output electrical signal, and performing feedback correction on the first output electrical signal to eliminate a noise to obtain first correction data; using the sensor to scan a correction specimen page to obtain a second output electrical signal, and performing the feedback correction on the second output electrical signal to eliminate a noise to obtain second correction data; calculating according to the first correction data, the second correction data and an electrical signal predetermined value to obtain third correction data; using the sensor to scan a to-be-detected object to obtain a third output electrical signal; and correcting the third output electrical signal according to the first correction data and the third correction data. In the detection method obtains an accurate detection result.

A document liveness detection method comprising using a hardware processor for prompting an end-user of an electronic device, having a camera, to provide an image sequence of a physical document whose orientation is undergoing change; and image-processing the image sequence to yield an output indication of whether or not the image sequence was generated by capturing a live or physical document; and providing the output indication to at least one computerized system or human.

Donation receiving apparatus has a denomination discriminator interfacing a storage area. The denomination discriminator has at least one sensor for sensing at least one physical characteristic of currency passing therethrough. A device controller interfaces a mobile communication device interface and the denomination discriminator. In use, the device controller establishes communication with the mobile communication device, detects a denomination using the at least one physical characteristic and transmits the denomination to the mobile communication device. The mobile communication device may execute an application controller which displays a graphical user interface on a digital display thereof which may display the denomination.

A medium processing device includes a first, second and third conveyance path, a classification section, a first, second and third switching unit, a first, second and third storage box and a controller. Each of the first, second and third conveyance paths has two ends. One end of the first conveyance path is connected to one end of the third conveyance path. One end of the second conveyance path is connected to the other end of the third conveyance path at a second side of the classification section opposite to the first side. The other end of the first conveyance path is connected to the other end of the second conveyance path. The controller controls the first conveyance path and the second conveyance path so that the first and second conveyance paths are driven independently from each other.
