 How can you stitch a lot of natural images to a single image?

 we look more into continuity of different images). All these abilities are present in us inherently.
 
 So our one basic question expands to more in number, but becomes more specific. **What are these

-Well, it is difficult to say how humans find these features. It is already programmed in our brain.

 But if we look deep into some pictures and search for different patterns, we will find something
 interesting. For example, take below image:

+A and B are flat surfaces and they are spread over a lot of area. It is difficult to find the exact
 location of these patches.
 
-C and D are much more simpler. They are edges of the building. You can find an approximate location,
-but exact location is still difficult. It is because, along the edge, it is same everywhere. Normal
-to the edge, it is different. So edge is a much better feature compared to flat area, but not good

-Finally, E and F are some corners of the building. And they can be easily found out. Because at
-corners, wherever you move this patch, it will look different. So they can be considered as a good

-Just like above, blue patch is flat area and difficult to find and track. Wherever you move the blue
-patch, it looks the same. For black patch, it is an edge. If you move it in vertical direction (i.e.
-along the gradient) it changes. Put along the edge (parallel to edge), it looks the same. And for

+patch it looks the same. The black patch has an edge. If you move it in vertical direction (i.e.
+along the gradient) it changes. Moved along the edge (parallel to edge), it looks the same. And for
 red patch, it is a corner. Wherever you move the patch, it looks different, means it is unique. So
 basically, corners are considered to be good features in an image. (Not just corners, in some cases
 blobs are considered good features).
 
 So now we answered our question, "what are these features?". But next question arises. How do we
-find them? Or how do we find the corners?. That also we answered in an intuitive way, i.e., look for
+find them? Or how do we find the corners?. We answered that in an intuitive way, i.e., look for
 the regions in images which have maximum variation when moved (by a small amount) in all regions
 around it. This would be projected into computer language in coming chapters. So finding these image
 features is called **Feature Detection**.
 
-So we found the features in image (Assume you did it). Once you found it, you should find the same
-in the other images. What we do? We take a region around the feature, we explain it in our own
-words, like "upper part is blue sky, lower part is building region, on that building there are some
-glasses etc" and you search for the same area in other images. Basically, you are describing the
-feature. Similar way, computer also should describe the region around the feature so that it can

 So in this module, we are looking to different algorithms in OpenCV to find features, describe them,
