Recognizing a harder problem. The reason behind the difficulties

character and digit from documents such as photographs which captured at a
street level is a very important factor in modern-day map making. For example,
automatically identify an address accurately from street view images of that
building. By using this information more precise map can be built and it can
also improve navigation services. Though normal character classification is
already a solved problem by computer vision but still recognizing digit or
character from the natural scene like photographs are still a harder problem.  The reason behind the difficulties may be the
non-contrasting backgrounds, low resolution, blurred images, fonts variation,
lighting etc.

approaches for classifying characters and digits from natural images were
separated into two channels. First segmenting the images to extract isolated
characters and the perform recognition on extracted images. And this can be
done using multiple hand-crafted features *1 er ref and template matching. *1

The main purpose of this project is to recognize the street view house
number by using a deep convolutional neural network.  For this work, I considered the digit
classification dataset of house numbers which I extracted from street level
images. This dataset is similar in
flavor to MNIST dataset but with more labeled data. It has more than
600,000-digit images which contain color information and various natural
backgrounds and collected from google street view images. To achieve the goal,
I formed an application which will detect the number of just image pixels. Here,
a convolutional neural network model with multiple layers is used to train the
dataset and detect the house digit number with high accuracy. I used the
traditional convolutional architecture with different pooling methods and
multistage features and finally got 91.1% accuracy
