I want to detect a car using Contourlet Transform from a color image. What are the steps to do it?
My plan: Image acquisiton-Preprocessing(segmentation)-Contourlet Transform-Feature Extraction-Classification-Featutre Matching-Object Detection
Am I right? If yes, which step should be started? Which segmentation method is appropriate for my image? Please do help me. I will be grateful to you.

if you have any idea how I could retrieve the rotate and crop values for the original image, that would be great.
alternatively, if you know of any other plug-in where I would be able to crop/rotate/edit the image that would be greatly appreciated.
I am building the app in a flutter.
I have this poster image:
I have to blend it with another image. I have to put this image on a picture of a building like this:
The rotated poster image has white pixels that I don't know how to get rid of.
Can someone please help me with code to paste this image on the building image? The front of the building.
Firstly find the four corner points of building where you want to blend image. Also find four corner points of your poster. Then use perspective transform and warpaffine to paste poster on image.
This http://www.learnopencv.com/homography-examples-using-opencv-python-c/ link may help you to get the idea but it is using OpenCV.
I have tried this using OpenCV C++ and I am getting following image after applying perspective transform. Let me know if you want this kind of results:
I want to mask some area (Blue and Red) in an image, I tried different methods but I couldn't get the solution that I want.
Here's the image I am using:
Here's the result that I want:
Please explain the code because I really want to learn how it works and implement it in my own understanding.
Any helps ? Thanks
For my website, I want to use the vector image as shown here: http://www.sketchappsources.com/free-source/226-iphone-5.html
It's an iPhone 5 that is tilted.
Now I need to add my image to the screen which means I need to 3D-tilt it. I've tried and searched a lot but couldn't figure out how to transform my image so that it fits the iPhone 5 screen.
Any help in guiding me how to 3D transform my image would be greatly appreciated!
Cheers,
Frank
I recently released a plugin solving the exact issue, it allows you to draw a shape with the Vector tool and then apply the content of an artboard into the area. It's called Magic Mirror, please take a look at http://magicmirror.design
I am creating an application in which i am displaying image view with image and processing brightness on the image using slider. I want that brightness should be done only on the selected part of image and not on the entire image.
I want the brightness should be processed only on the central part of the image without using openGl Image processing.
Please help me to solve this problem. Hey guys Please help me its important for me.
There are several ways to accomplish this. One is to overide the drawRect: UIView method and use a mask. Another is to draw the bitmap yourself in a CGContext. Yet another is with OpenGL.
What have you tried?
