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 5):
The fingerprint image recognition method according to  claim 4 , acquiring the coordinates of the edge pixel points in each column of the target image comprising:\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.
