In step s101, using the first convolutional neural networks, the first picture is carried out with Face datection, obtain the first picture The first face characteristic, wherein, the first face is characterized as the first picture under first resolution, in the first convolutional neural networks The first default layer output characteristic.
Wherein, above-mentioned Face datection refers to go out the position of the face in a width picture by the first convolution neural network recognization And size information, generally, need for a width picture to zoom to multiple different resolution, and to multiple different resolutions Picture under rate using position and the size of the first convolution neural network recognization face therein, divides in conjunction with multiple differences one by one Under resolution, the position of obtained face and size information are analyzed, thus obtaining the accurate location of the face in a secondary picture Information with size.
In this step, when carrying out Face datection to the first picture, refer to carry out complete Face datection to the first picture, that is, According to above-mentioned method for detecting human face, set the picture scaling resolution of the first picture first, for example can be by the figure of the first picture Piece scaling resolution sets gradually as 0.3,0.5,0.7,1.And then, using the first convolutional neural networks under every kind of resolution First picture carries out Face datection, obtains the size and location information of the face in the first picture under every kind of resolution.And then, By the face size and location information under every kind of resolution is determined with the accurate size and location letter of face in the first picture Breath.Wherein, when Face datection being carried out to the first picture under every kind of resolution using the first convolutional neural networks, the first convolution god Each layer through network all can export corresponding eigenvalue.In this step, after completing the Face datection of the first picture, can select The output characteristic of a certain certain layer in the first convolutional neural networks under first resolution carries out human face similarity inspection as following The first face characteristic during survey, wherein, the certain layer in first resolution and the first convolutional neural networks can be as needed Flexibly it is configured.
In step s102, using the first convolutional neural networks, face inspection is carried out under first resolution to second picture Survey, obtain second picture under first resolution, the second face characteristic of the default layer of first in the first convolutional neural networks.
In hypothesis above-mentioned steps s101, the first resolution corresponding to the first face characteristic of the first picture is resolution a, The layer in the first convolutional neural networks corresponding to first face characteristic is layer b, then, after selecting resolution a and layer b, this In step, using the first convolutional neural networks, Face datection can be carried out under resolution a to second picture, when completing resolution a Under the Face datection of second picture after, then obtain second picture in this Face datection, the layer b of the first convolutional neural networks Output characteristic value, using this output characteristic value as second picture the second face characteristic.
In step s103, judge whether above-mentioned first face characteristic and the similarity of above-mentioned second face characteristic are more than in advance If threshold value, if it is determined that the first picture and second picture are face similar pictures.
The threshold value of face characteristic similarity can be pre-set, when getting the first of the first picture through abovementioned steps After second face characteristic of face feature and second picture, the first face characteristic and the second face characteristic are compared, if ratio The threshold value pre-setting is more than to the similarity going out, then can determine that the first picture and second picture are face similar pictures, no Then it is possible to determine that the first picture and second picture are not human face similarity pictures.
In above process, after complete Face datection is carried out to the first picture, only one has been carried out to second picture Plant the Face datection under resolution, i.e. in the process, the Face datection of second picture does not simultaneously complete, but just can basis A kind of Face datection result under resolution for the second picture detects come the human face similarity to carry out the first picture and second picture, That is, the present embodiment achieves and has carried out human face similarity detection during Face datection simultaneously, will human face similarity detection fusion During Face datection, complete Face datection and the first picture and second of the first picture using same algorithm simultaneously The human face similarity detection of picture.And in correlation technique, Face datection and human face similarity are detected as two separate processes, people Face approx imately-detecting independently must be carried out after the completion of the Face datection of picture, and therefore, compared to correlation technique, the present embodiment is realized Face datection and the fusion of human face similarity detection, thus greatly improve the efficiency of human face similarity detection.
As one kind preferred embodiment, above-mentioned first convolutional neural networks can be full convolutional neural networks (fully Convolutional networks, abbreviation fcn), wherein, fcn network is by the full articulamentum in traditional convolutional neural networks Make convolutional layer into, to form a kind of full convolution Rotating fields such that it is able to obtain more more accurate than traditional convolutional neural networks Training result.
In the above-described embodiments, first resolution can scale minimum point in resolution for the corresponding picture of the first picture Resolution.
For the first picture, all pictures being set are needed to scale the Face datection under resolution, that is, first What picture was carried out is complete Face datection, and it is only necessary to the set all pictures of execution scale for second picture The Face datection under lowest resolution in resolution, selects lowest resolution to carry out Face datection, can not only protect Card obtains the result of follow-up human face similarity detection, meanwhile, compared to holding of the Face datection under other resolution, lowest resolution Scanning frequency degree faster, therefore can select lowest resolution can also lift the efficiency of human face similarity detection.
In the above-described embodiments, the in the first convolutional neural networks first default layer is last layer volume in fcn network Lamination.
Multiple convolutional layers are included in fcn network, when Face datection is carried out using fcn network to specific picture, Each layer of fcn network all can output characteristic value, the information of the eigenvalue that layer more rearward is exported can more enrich and accurately. Therefore, select last layer of convolutional layer as default layer, for the first picture and second picture, all select the output characteristic of this layer As the feature compared, ensure that the result of comparison is also more accurate.
It should be noted that for actual needs, in the layer selecting to carry out aspect ratio pair it is also possible to select fcn net Other layers in network, layer for example second from the bottom.
On the basis of above-described embodiment, the present embodiment is related to a kind of processing procedure before face characteristic compares, i.e. Before above-mentioned steps s102, also include:
Judge whether the shooting time of second picture and the difference of the shooting time of the first picture are less than predetermined threshold value, if No it is determined that the first picture and second picture are not face similar pictures.
User, when shooting picture, is often continuously shot several pictures in same position, to ensure to photograph more preferably Effect.That is, several pictures of human face similarity can be formed at short notice, the common feature of these pictures except human face similarity it Outward, shooting time is also very close to.Therefore, it is possible to be entered using these pictures dependency in time in the present embodiment Row human face similarity judges.Specifically, before second picture is carried out with the Face datection under a kind of resolution, obtain respectively first Take the shooting time of the first picture and second picture, if it is judged that the difference of the shooting time of the first picture and second picture surpasses Cross certain threshold value, such as difference exceedes half a minute or 1 minute, then can directly determine that this two width picture is not human face similarity figure Piece is it is no longer necessary to carry out the Face datection of follow-up second picture and the comparison of face characteristic.And if it is judged that the first picture It is less than or equal to set threshold value with the difference of the shooting time of second picture, then proceed the face of follow-up second picture Detection and the comparison of face characteristic.
In the present embodiment, primary election during human face similarity detection is used as by the shooting time of the first picture and second picture Mode, if not meeting the condition of shooting time, can directly determine that the first picture and second picture are not similar pictures, and Do not need to execute follow-up Face datection again and face characteristic compares, therefore, improve the efficiency of human face similarity detection further.
On the basis of above-described embodiment, the present embodiment is related to another kind of processing procedure before face characteristic compares, i.e. Before above-mentioned steps s102, also include:
Judge whether the length and width of second picture is consistent respectively with the length and width of the first picture, if it is not, then true Fixed first picture and second picture are not face similar pictures.
If same user or the multiple user of identical are continuously shot several pictures within a short period of time, these pictures Length and width should be consistent, therefore, in the present embodiment, before carrying out Face datection to second picture, first determines whether Whether the first picture is consistent respectively with the length and width of second picture, i.e. whether the length of the first picture is equal to second picture Length, whether the width of the first picture be equal to the width of second picture, if having one to be unsatisfactory in this two conditions so that it may To determine that the first picture and second picture are not face similar pictures;If this two conditions all meet, proceed follow-up The Face datection of second picture and face characteristic comparison.
In the present embodiment, it is used as another during human face similarity detection by the length and width of the first picture and second picture A kind of primary election mode, if not meeting the consistent condition of length and width, can directly determine the first picture and the second figure Piece is not similar pictures, without executing follow-up Face datection and face characteristic comparison again, therefore, improves people further The efficiency of face approx imately-detecting.
It should be noted that during actual face approx imately-detecting, the method for the present embodiment and aforementioned judgement picture are clapped The method taking the photograph the time can be simultaneously using it is also possible to select one of which to use, when both approaches use simultaneously, this Bright its sequencing is not limited, can flexibly be configured as needed.
On the basis of above-described embodiment, the present embodiment is related to judge that the first picture and second picture are face similar diagram Processing procedure after piece, i.e. after above-mentioned steps s103, also includes:
If the first picture and second picture are face similar pictures, according to the second face characteristic of second picture, determine Other face similar pictures of first picture.
That is, when determining after the first picture and second picture are face similar pictures it is possible to second picture as base Standard is identifying other similar pictures of the first picture.Specifically it is assumed that the second face characteristic of second picture is in resolution c Under, the output characteristic that obtained in the d layer of the first convolutional neural networks, then when the human face similarity carrying out next width picture detects When, next width picture is narrowed down to resolution c, and using the first convolutional neural networks, next the width picture under resolution c is entered Row Face datection, obtains the output characteristic of wherein d layer, the second feature of this output characteristic and second picture is compared, If comparison result is more than the predetermined threshold value in above-mentioned steps s103, can determine that next width picture is the first picture and second The human face similarity picture of picture.That is, only by the 3rd picture and second picture are compared feature it is possible to determine the 3rd picture with First picture and the human face similarity of second picture, the like, every time only need to be by next width picture and last width figure before Piece carries out aspect ratio to it is possible to determine the human face similarity of next width picture and all face similar pictures before.
It should be noted that it is also possible to pass through before the human face similarity detection carrying out second picture and next width picture Aforesaid judge shooting time and/or judge the method for length and width and to carry out primary election, detailed process referring to previous embodiment, Here is omitted.
In the present embodiment, after determining second picture and the first picture is face similar pictures, carrying out and next width figure In this way it is no longer necessary to the participation of the first picture during the human face similarity detection of piece, but only need second picture and next width picture Compare, the result of comparison can be equally applicable to the first picture, it is achieved thereby that be only performed once human face similarity just detecting Can determine the human face similarity of several pictures, thus improving the efficiency of human face similarity detection further.
