DATA GENERATOR KERAS EXAMPLE GENERATOR
There are various methods available for the class of image data generator that includes – It represents the factor of rescaling which can have value either channels last or channels first. It stands for the data format of the image. It is a float value and is used for the specification of the fraction images that are used for the purpose of validation. It is used for the arrays that are generated. It can be float or int or 1-dimensional array similar to that of width sift range but in this case, it applies to the total height. When the value is 0 then the float valve can be possibly between the range of -1.0 to +1.0. When the value of the width shift range is 2 then the value of integer can be -1,0 or 1. Integer value stands for the pixels count that can be between the range of – to + width shift range. The 1-dimensional array stands for the array containing the random elements. If the value of this float is less than 1 or it is pixels if the value is greater than or equal to 1. Here, float value of the fraction of the width in total. It is a float value used for the 1-dimensional array or integer. This is an integer value for defining the range of degrees in random rotations. The default value of this argument when not specified is 1e-6 and is used for the representation of epsilon for ZCA whitening.īoolean value to represent whether to apply or not the ZCA whitening. It is a Boolean value for referring to std to divide each of the individual input values. The boolean value is used to represent whether the input data is to be divided by using the std that is defined by the set of data in a feature wise manner. This is also a Boolean value for the specification of setting the value of the mean for each of the individual samples to 0.
It is a Boolean value used for setting the value of the input to 0 for the particular data set in a feature-wise manner. The definition of the class of image data generator is as shown below containing all the arguments or parameters that helps to define the behavior and way of performing the process. The syntax that can be used for using ImageDataGenerator is as defined in its class of it. How many images will be generated depends on the size of the batch and the input data set that contains a specific number of inputs? For example, if the size of the batch is defined as 10 and we pass 1000 images in the input of outset of data then the number of images that will generate in each and every iteration of the training will be 10. We can make the use of ImageDataGenerator class by passing the appropriate parameters and passing the required input to it. There are various methods and arguments of the image data generator class that helps to define the behavior of the data generation. We can loop over the data in batches when we make use of the image data generator in Keras. Keras image data generator is used for the generation of the batches containing the data of tensor images and is used in the domain of real-time data augmentation.
