Abstract:
A fingerprint image recognition method is provided. The method includes: acquiring a target image from a captured texture image; acquiring a target shape feature corresponding to the target image, the target shape feature being configured to represent a shape feature of the target image; and when the target shape feature matches with a preset finger shape feature, determining to perform a fingerprint recognition on the texture image. Also provided in the present invention are a fingerprint image recognition apparatus and a terminal.

Claim (Index 15):
The fingerprint image recognition apparatus according to  claim 14 , the instruction execution system being further configured by the instructions to implement an act of acquiring the coordinates of the edge pixel points in each column of the target image by performing acts of:\n for each column of the target image, acquiring a pixel value of each pixel in the column; searching a pixel point with the pixel value greater than or equal to a preset pixel value sequentially from a first column to a last column; determining the pixel point with the pixel value greater than or equal to the preset pixel value and with a column number smaller than a maximum column number as a first edge pixel point of a row including the first edge pixel point, a row number and the column number of the first edge pixel point forming a coordinate of the first edge pixel point; searching the pixel point each with the pixel value greater than or equal to the preset pixel value sequentially from the last column to the first column; and determining the pixel point with the pixel value greater than or equal to the preset pixel value and with the column number greater than a minimum column number as a second edge pixel point of a row including the second edge pixel point, a row number and the column number of the second edge pixel point forming a coordinate of the second edge pixel point.
