However, if the type of the original image is a grayscale image, the grayscale image has a poorer display effect on the target object in the image than a color image, a contour image, or a contour gradient image. Therefore, the applicant proposes that when the image type of the original image is a gray image, a pre-trained recognition model is adopted to perform contour recognition on the target object in the image of the region of interest. In an embodiment, optionally, a training image set is obtained, and a target object in the training image set is labeled; and inputting the marked training image set serving as a training sample into the initial recognition model, and adjusting model parameters of the initial recognition model according to an output result to obtain a trained recognition model.

Program modules 42 generally carry out the functions and/or methodologies of the described embodiments of the invention.
The processing unit 16 executes various functional applications and data processing, such as implementing an image measurement method provided by an embodiment of the present invention, by running a program stored in the system memory 28.
Through the equipment, the problem that finger touch cannot be accurately positioned is solved, so that the region-of-interest image can be accurately selected even under the touch condition of the finger, and the convenience and accuracy of image measurement are improved.
EXAMPLE six
An embodiment of the present invention further provides a storage medium containing computer-executable instructions, which when executed by a computer processor, perform an image measurement method, the method including:
receiving a touch operation instruction input by a user based on an original image in a first display window, wherein the touch operation instruction comprises a click operation instruction and/or an image sliding instruction;
acquiring an interesting area image corresponding to the touch operation instruction in the original image, and displaying the interesting area image in a second display window based on a preset scaling;
when an image measurement instruction is detected, measurement data of a target object in the region-of-interest image is determined.
Computer storage media for embodiments of the invention may employ any combination of one or more computer-readable media. The computer readable medium may be a computer readable signal medium or a computer readable storage medium. A computer readable storage medium may be, for example, but not limited to, an electronic, magnetic, optical, electromagnetic, infrared, or semiconductor system, apparatus, or device, or any combination of the foregoing. More specific examples (a non-exhaustive list) of the computer readable storage medium would include the following: an electrical connection having one or more wires, a portable computer diskette, a hard disk, a Random Access Memory (RAM), a read-only memory (ROM), an erasable programmable read-only memory (EPROM or flash memory), an optical fiber, a portable compact disc read-only memory (CD-ROM), an optical storage device, a magnetic storage device, or any suitable combination of the foregoing. In the context of this document, a computer readable storage medium may be any tangible medium that can contain, or store a program for use by or in connection with an instruction execution system, apparatus, or device.
A computer readable signal medium may include a propagated data signal with computer readable program code embodied therein, for example, in baseband or as part of a carrier wave. Such a propagated data signal may take many forms, including, but not limited to, electro-magnetic, optical, or any suitable combination thereof. A computer readable signal medium may also be any computer readable medium that is not a computer readable storage medium and that can communicate, propagate, or transport a program for use by or in connection with an instruction execution system, apparatus, or device.
Program code embodied on a computer readable medium may be transmitted using any appropriate medium, including but not limited to wireless, wireline, optical fiber cable, RF, etc., or any suitable combination of the foregoing.
Computer program code for carrying out operations for aspects of the present invention may be written in any combination of one or more programming languages, including AN object oriented programming language such as Java, Smalltalk, C + +, and conventional procedural programming languages, such as the "C" programming language or similar programming languages.
Of course, the storage medium provided by the embodiment of the present invention contains computer-executable instructions, and the computer-executable instructions are not limited to the above method operations, and may also perform related operations in the image measurement method provided by any embodiment of the present invention.
It is to be noted that the foregoing is only illustrative of the preferred embodiments of the present invention and the technical principles employed. It will be understood by those skilled in the art that the present invention is not limited to the particular embodiments described herein, but is capable of various obvious changes, rearrangements and substitutions as will now become apparent to those skilled in the art without departing from the scope of the invention. Therefore, although the present invention has been described in greater detail by the above embodiments, the present invention is not limited to the above embodiments, and may include other equivalent embodiments without departing from the spirit of the present invention, and the scope of the present invention is determined by the scope of the appended claims.
