Imagine how much more valuable your data would be to your business if your document-intake solution could extract data from images as seamlessly as it does from the text.
Thanks to deep learning, intelligent document processing (IDP) is able to combine various AI technologies to not only automatically classify photos, but also describe the various elements in pictures and write short sentences describing each segment with proper English grammar.
IDP leverages a deep learning network known as CNN (Convolutional Neural Networks) to learn patterns that naturally occur in photos. IDP is then able to adapt as new data is processed, using Imagenet , one of the biggest databases of labeled images, which has been instrumental in advancing computer vision.
One of the ways this type of technology is implemented with impact is in the document-heavy insurance industry. Claims processing starts with a small army of humans manually entering data from forms.
In a typical use case , the claim includes a set of documents such as: claim forms, police reports, accident scene and vehicle damage pictures, vehicle operator driver's license, insurance copy, bills, invoices, and receipts. Documents like these aren’t standard, and the business systems that automate most of the claims processing can’t function without data from the forms.
To turn those documents into data, the Convolutional Neural Networks are trained using GPU-accelerated deep learning frameworks such as Caffe2, Chainer, Microsoft Cognitive Toolkit, MXNet, PaddlePaddle, Pytorch, TensorFlow, and inference optimizers such as TensorRT.
Neural networks were first used in 2009 for speech recognition, and were only implemented by Google in 2012. Deep learning, also called neural networks, is a subset of machine learning that uses a model of computing that's very much inspired by the structure of the brain.
"Deep learning is already working in Google search and in image search; it allows you to image-search a term like 'hug.' It's used to getting you Smart Replies to your Gmail. It's in speech and vision. It will soon be used in machine translation, I believe." said Geoffrey Hinton, considered the Godfather of neural networks.
Deep Learning models, with their multi-level structures, as shown above, are very helpful in extracting complicated information from input images. Convolutional neural networks are also able to drastically reduce computation time by taking advantage of GPU for computation, which many networks fail to utilize.
Let’s take a deeper dive into IDP’s image data preparation using deep learning. Preparing images for further analysis is needed to offer better local and global feature detection, which is how IDP enables straight-through processing and drives ROI for your business. Below are the steps:
IMAGE CLASSIFICATION: For increased accuracy, image classification using CNN is most effective. First and foremost, your IDP solution will need a set of images. In this case, images of beauty and pharmacy products are used as the initial training data set. The most common image data input parameters are the number of images, image dimensions, number of channels, and number of levels per pixel.
With classification, you are able to categorize images (in this case, as beauty and pharmacy). Each category again has different classes of objects as shown in the picture below:
DATA LABELING :It’s better to manually label the input data so that the deep learning algorithm can eventually learn to make the predictions on its own. Some off the shelf manual data labeling tools are given here . The objective at this point will be mainly to identify the actual object or text in a particular image, demarcating whether the word or object is oriented improperly, and identifying whether the script (if present) is in English or other languages.
To automate the tagging and annotation of images, NLP pipelines can be applied. ReLU (rectified linear unit) is then used for the non-linear activation functions, as they perform better and decrease training time.
To increase the training dataset, we can also try data augmentation by emulating the existing images and transforming them. We could transform the available images by making them smaller, blowing them up, cropping elements etc.
USING RCNN: With the usage of Region-based Convolutional Neural Network (aka RCNN), locations of objects in an image can be detected with ease. Within just 3 years the RCNN has moved from Fast RCNN, Faster RCNN to Mask RCNN, making tremendous progress towards human-level cognition of images. Below is an example of the final output of the image recognition model where it was trained by deep learning CNN to identify categories and products in images.

FAQ On Deep Learning Image Processing
Which algorithm is best in deep learning? Choosing a deep learning algorithm depends on the specific problem that you are trying to solve. Some commonly used algorithms in deep learning include convolutional neural networks (CNNs), recurrent neural networks (RNNs), and long short-term memory networks (LSTMs). Each of these algorithms has its own advantages and disadvantages, so it is important to select the one that is best suited for your particular problem. In general, CNNs are good for image classification and object detection tasks, while RNNs and LSTMs are better for sequential data such as text or time series data.
Does Deep Learning Image Processing have any real-life application? Yes, deep learning can be applied to real-life applications. Examples include self-driving cars, video games, image analysis, computer vision, trading algorithms, and various other applications.
How does a deep learning model work? A deep learning model is a neural network that is composed of multiple layers. The first layer is the input layer, which receives input data. The second layer is the hidden layer, which transforms the input data into a representation that can be used by the output layer. The output layer produces the desired output.
Which tools/programming languages should I use to create Deep Learning models? There are many programming languages that can be used to create Deep Learning models. The most popular tools include TensorFlow, Keras, and PyTorch. These tools allow developers to easily create and train complex Deep Learning models. In terms of programming languages, Python is the most popular language for Deep Learning. This is because Python has several powerful libraries that make it easy to develop Deep Learning models. However, it is also possible to use other languages such as Java or C++.
Does training deep learning models require a lot of data? Yes, deep learning requires lots of labeled training data than traditional machine learning models. This is because deep learning models are more complex and have more parameters that need to be trained.
