Using full articulamentum 5 (IP5) as the top layer of pond layer 4, full articulamentum 5 is output as 4096, in order to prevent due to
The over-fitting that data are very few and cause, adds Dropout layers, for neutral net unit with 0.5 on the full articulamentum
Probability temporarily abandons it.
Using full articulamentum 6 (IP6) as the top layer of full articulamentum 5 (IP5), full articulamentum 6 is output as 4096, similar
, dropout layers are added equally on full articulamentum 6.
The top layer of full articulamentum 6 (IP6) is used as using full articulamentum 7 (IP7).
Full articulamentum 7 (IP7) is output as 6, i.e., data set input is divided into six classes.On the top of last full articulamentum
Portion is plus the Accuracy layers of the description current training characteristics of network and Loss layers.
Accuracy layers:Accuracy rate is exported, often trains 100 times and network is once tested, is test number of iterations with 80
Amount.
Loss layers:Loss is exported, passes through loss variation tendency, it can be determined that the state that network is currently trained.Work as train
When loss and test loss constantly decline, illustrate that network is still being studied hard.
Meanwhile, also it is directly output to Accuracy and Loss layers as the data Layer of the bottom.
Identification by the convolutional neural networks after trained to specific cartoon figure's image:The LMDB that data Layer is inputted
The data of type are changed to the data input described with 4 dim parameters.By the output layer Softmax With of former training network
Loss is changed to Softmax, and that exported during training is loss, is changed to export prob during test.
Step 5, by the depth convolutional neural networks of trained completion animation cartoon personage's picture after calibration is entered
Row identification, and recognition result is exported, as a result it is shown in text formatting on screen, five kinds of expression institutes of an indicating probability highest are right
The probability answered, and sort from high to low;Specifically:
User uploads the facial expression image of a cartoon figure;Any present age conventional animated character can be used, the figure
The conventional expression of one kind that picture illustrates the personage (meets six kinds of the angry, glad, sad, surprised of model needs, detest and fear
One of expression).Two cartoon figure's facial expression pictures are randomly choosed, specific picture can refer to Fig. 4, respectively one displaying life
The cartoon figure that the cartoon figure of gas meter feelings and a displaying are happily expressed one's feelings.
The image is pre-processed, reference format picture is converted into, that is, obtains the image of 256*256 pixels, and by coloured silk
Chromatic graph piece is converted into greyish white image of the gray value in [0,255], the identification work so as to after.
By having trained the depth convolutional neural networks of completion, the input picture of standardized format is identified;Output
Recognition result, presentation form as a result is the occupied probability of first five class expression.
Two selected pictures have obtained gratifying recognition effect, and specific recognition result can refer to following table:
Table 1 randomly chooses the recognition result of two cartoon figure's facial expression pictures
The test result that six classes expression for the FERG picture libraries used in training is tested respectively is as shown in the table:
The test result that table 2 is tested respectively for the six classes expression of the FERG picture libraries used in training
