Referring to fig. 2, an embodiment of the present invention provides an image processing method, including:
wherein, the touch operation is a manual touch operation. The step of detecting the touch operation of the user on the picture comprises at least one of the following steps:
detecting sliding operation of a user on a picture in a closed sliding track mode;
detecting a smearing operation of a user on a picture;
a pressing operation of a user on a picture is detected.
The first touch operation is an operation for triggering selection of a target area to be processed, the first touch operation may be a sliding operation in which a sliding track is in a closed form, and the first touch operation may slide along any direction, the track may be in a closed form, and the target area is determined according to a range surrounded by the sliding track.
When the painting operation is performed on a picture, the target area is determined according to the range of the painting operation, and the painting operation slides repeatedly.
The method can also be used for pressing operation, and when the pressing pressure exceeds a set threshold value, an area within a preset range of the contact point of the pressing operation is set as a target area.
Wherein, the preset encryption operation is the pressing operation, the sliding operation in the form of closed sliding track or the smearing operation, etc.; when the above operation is detected, a first operation characteristic is acquired.
The first operation characteristic may include fingerprint information, sliding track information, and the like; and determining a target area to be processed according to the first operation characteristic.
Preferably, step 203 comprises: extracting an operation area in the first operation characteristic;
and determining the operation area as a target area, or performing edge detection on the operation area, and determining an image area surrounded by the detected outline as the target area.
The first operation feature comprises an operation area of the first touch operation, the target area to be processed is the operation area or an area comprising a target object to be processed, a dividing line between different feature areas in the target area can be extracted by using the difference of an object and a background in the aspects of gray scale, color or texture features of a picture through a picture edge detection technology, an image area surrounded by the detected outline is determined as the target area, and therefore a main body, namely the target object, in the area selected by a user on the picture is identified.
wherein, the first fingerprint information of the first touch operation is extracted, namely the fingerprint information of the finger executing the first touch operation
The first corresponding relation comprises the corresponding relation between fingerprint information and an encryption mode, the encryption mode comprises the step of shielding a target area through a shielding object or conducting mosaic processing on the target area, and after the first fingerprint information is determined, the target encryption mode can be determined.
And step 206, encrypting the target area according to the target encryption mode.
Optionally, after the target area is identified, the user may be prompted whether to encrypt the target area, if the user feedback is yes, the target area is encrypted,
wherein step 206 comprises: hiding the target area according to the target encryption mode;
and recording a second corresponding relation between the target area and the first fingerprint information.
In this step, the target area is hidden according to the target encryption mode, and the corresponding relation between the target area and the first fingerprint information is recorded, so that subsequent image decryption is facilitated.
Preferably, the hiding the target area according to the target encryption manner includes:
covering an image area where the target area is located by using a preset object, wherein the preset object is a preset image or a non-target area extracted from the image;
or mosaic processing is carried out on the target area.
In the first mode, a preset object is adopted to cover an image area where the target area is located, and the preset object can be a preset image or a non-target area extracted from the image; hiding the target area and filling the hidden part; the preset object is a preset image, such as a star head portrait, an animal head portrait and a cartoon head portrait, replacing a target area; non-target areas, such as scene information, extracted from the picture, may be hidden and replaced with additional scenes on the picture: for example, a flower can be hidden by using another grass; when a person is hidden, the avatar of another person may be used.
In the second mode, the target area is subjected to mosaic processing, which means that details of color levels in a specific area of an image are degraded and color blocks are disturbed, so that the target area can be effectively shielded and cannot be identified.
Preferably, the step of mosaic processing the target area includes:
acquiring a preset mosaic type corresponding to the first fingerprint information;
and performing mosaic processing on the target area according to the mosaic type.
The user can correspond the fingerprint information of the user to the mosaic pattern form through the editing interface. One fingerprint may correspond to one mosaic type, or several fingerprint combinations may correspond to a certain mosaic pattern form. Therefore, when the first fingerprint information is acquired, the pre-stored mosaic type of the fingerprint information is determined, and the target object is subjected to mosaic processing according to the form.
Optionally, the user may use more than two types of mosaic information to perform coding on the area in a combined manner, or may perform a painting operation on one mosaic through other fingers to add mosaic patterns, thereby realizing superposition of multiple mosaics, and increasing security of encryption to prevent decryption of fingerprint information of one finger after the fingerprint information is misrecognized.
Preferably, after the step of encrypting the target area, the method includes:
if a second touch operation matched with the preset decryption operation is detected;
extracting second fingerprint information of the second touch operation;
and if the second fingerprint information is matched with the first fingerprint information, decrypting the target area.
In this step, the second touch operation is an operation for restoring and displaying the encrypted target area, and corresponds to the first touch operation. When a second touch operation of the user on the picture is received, fingerprint information of the second touch operation is extracted. If the recorded first fingerprint information contains first fingerprint information matched with the second fingerprint information, searching a target area corresponding to the first fingerprint information according to the second corresponding relation, namely the target area corresponding to the second fingerprint information, and decrypting the target area.
Specifically, the step of performing decryption processing on the target area includes:
determining a target area corresponding to the matched first fingerprint information according to the second corresponding relation;
and restoring and displaying the target area.
After the first fingerprint information corresponding to the second fingerprint information is determined, the target area corresponding to the first fingerprint information is searched according to the second corresponding relation, namely the target area corresponding to the second fingerprint information is found, and the target area is restored and displayed.
Therefore, after the second fingerprint information is identified, the target object can be restored and displayed, and the original image before the image processing is obtained, so that only the processed image needs to be stored, and two images do not need to be stored at the same time; and the target object can be not displayed for other users, the privacy of the picture is improved, and the target object is restored and displayed only when the user needs to check the target object.
Preferably, the step of displaying the target area by restoring includes:
eliminating the display of a preset object covering the target area;
or demosaicing the target area.
The restoring and displaying of the target area comprises the step of eliminating the display of the preset object covered on the target area for the picture with the preset object covering, or the step of demosaicing the picture subjected to mosaic processing.
As a first example, referring to fig. 3, the method for processing a picture of an occlusion target object by mosaic processing shown in fig. 3 mainly includes the following processes:
The user can correspond the fingerprint information of the user to the mosaic pattern form in advance through the editing interface. One fingerprint can correspond to one mosaic type, or a plurality of fingerprint combinations can correspond to a certain mosaic pattern form; after setting, the system stores relevant configuration, and when the mobile terminal performs picture processing, the mosaic type preset by the user and corresponding to the fingerprint is obtained.
I.e. the user applies a finger over the picture to paint a certain area. For example, a user selects a picture to be edited, a position on the picture to be subjected to mosaic adding is smeared by a finger, mosaic adding to an image area can be realized by adding mosaic to the image area clockwise, and mosaic information is smeared and removed in a counterclockwise direction during decoding;
The system firstly identifies fingerprint information of a user, finds out a stored mosaic pattern form corresponding to the fingerprint information at the background, adds a mosaic with a corresponding form to a user smearing area on a picture, the user can use a mode of combining more than two mosaic information to beat codes to the area, and can also smear and beat a plurality of mosaic patterns on one mosaic, the superposition effect of various mosaics can be like a mixture of several colors, for example, a layer of blue mosaic is added on a pure red mosaic, the mosaic pattern is green, when the mosaic is removed, the user scrapes one layer with different fingers, then scrapes one layer, and finally displays original image information;
and 304, setting a mosaic pattern corresponding to the mosaic type for the target area, and recording the corresponding relation between the first fingerprint information and the target area.
Setting a mosaic pattern corresponding to the mosaic type for the target area, confirming and storing the picture after the user finishes processing the picture, and storing the mosaic information and the original pattern information of the picture and the fingerprint information of the user by the system;
and 305, detecting a second smearing operation of the user finger on the target area, and extracting second fingerprint information of the second smearing operation.
When the user wants to remove the mosaic pattern, fingers smear the mosaic area, and second fingerprint information of the second smearing operation is extracted. The mosaic can be gradually removed in the process of smearing the fingers, and the image is displayed again, so that the operation effect similar to scratch is achieved.
And step 306, if the second fingerprint information is matched with the first fingerprint information, decrypting the picture.
The system identifies the fingerprint information of the user, and if the second fingerprint information is matched with the first fingerprint information, the mosaic on the pattern is gradually removed along with the smearing of the finger of the user, and the original image information is displayed.
As a second example, referring to fig. 4, the picture processing flow shown in fig. 4 mainly includes the following steps,
The touch operation may be sliding of a closed track by a user, smearing of a fingerprint, or pressing of a certain area on an image, and extracting of first fingerprint information.
Referring to fig. 5, a user slides a finger on a picture to select a part to be hidden, for example, the user wants to hide a main body at C on the picture, circles out an area at C by sliding the finger or directly paints and presses the area at C, and identifies an object D in the area selected by the user on the picture by an edge detection technology.
The system marks the extracted object D and prompts a user whether to hide the block area;
The effect diagram after concealment is seen in fig. 6.
And the user slides, presses or paints the fingerprint again on the area of the hidden image, and extracts the second fingerprint information at the moment.
When a user wants to view the image of the hidden area, the user can smear or press the area of the hidden image information through finger fingerprints, and the hidden image is gradually displayed in the smearing process of the user;
and step 405, judging whether the second fingerprint information is matched with the first fingerprint information.
And identifying whether the second fingerprint information is correct.
And step 406, if the second fingerprint information is matched with the first fingerprint information, decrypting the target area.
And if the matching is carried out, displaying the object D.
In the embodiment of the invention, the first touch operation is received, the first fingerprint information of the first preset operation is extracted, the target area which needs to be encrypted by the user is determined according to the first touch operation, the encryption of the target area in the picture can be realized according to the fingerprint information, the operation is convenient and fast, and only the processed picture needs to be stored, so that the storage space of the mobile terminal is saved, and the picture can be encrypted and the original picture can be restored; and the picture hiding mode can be mosaic processing or blocking object processing, so that the use experience of a user is improved.
