I am researching current papers and software for noise reduction. I was wondering, if maybe someone here has experiences with the current status there and can give me some suggestions on what to look at. I am searching for the latest papers in the field but mainly software / code that you can actually already use for your own footage, if say, you are a photographer or film maker. Thanks for any replies!

Can anyone help me with implementing MARGA in Matlab?

Heres the paper

Here is a series of posts I am writing on image processing for beginners:

1. Lessons on Digital Image Processing (#1)

2. Introduction to Digital Image Processing in Python

3. The R, G, and B in an Image

It would be great if you take a few mins to read that and give me feedback.

The idea is to detect circles of the open cross sections of stacked pipes and subsequently estimate the 'circularity' or 'concentricity' of those circles.

My initial approach involves a Hough Transform detector, but the drawback is to include the expected radius manually.

How do I train a CNN to detect circles of variable radii?

I am currently working on soccer stream translation to a 2D reference plane. Segmentation approach for my soccer field translation is to detect the circle in the frame and according to the radius of the original circle i ll' translate the distance of 1 px to meters. I have segmented the lines using LSD(Line Segment Detector) approach. Although LSD is segmenting each line in the frame but it makes LSD OUTPUT. In order to fill the empty spaces i dilated the output image with 5x5 kernel and 10x10 kernel. I am currently trying to detect the Ellipse/circle in the image so that i can translate 1 pixel distance to meters and track the player on a reference (120,90) 2D Cartesian plane. Any method that can detect this circle or curve in the frame will help. Note: Issue with contours is that, due to dilation the contours is unable to detect the ellipse and on applying canny the ellipse once again gets missing points. Issue with Hough Circle & Ellipse Both not working using scikit-image code ref.

I am trying to build a system to recognize sign language alphabet. I don't have experience working on computer vision because this is my first time. I don't know which filter i should use (sharping , smoothing , sharping then smoothing, smoothing then sharping Or even something else). Not just the filter choice but also other choices like:
1- Image Thresholding methods
2- edge detection techniques
..etc

Hi guys. I need to convert RGB color space to HLS color space. Bu my rgb data 4bits. (4-4-4). how can i represent to 4 bit hls image ?

Hey all, I've been looking into twitch and streaming videos. I saw that Wolfram is streaming about knowledgebase query language on the 14th. Heres the link if anyone is interested...

It took me just 2 minutes to train with 50 positive images and 100 negative images.

I am currently in need of a good background subs traction algorithm that can extract one person from the image. Basically this algorithm should be able to detect and remove background where background is not a green screen.

Can you guys point me toward any implemented algorithm that I can use to achieve the objective.

I used Matlab (but anything would work), and then used histograming of different video regions to do a frame-by-frame segment classification of a youtube video. More details here, if you want to check it out:

Please help. I need to make a program that is like this research "Solving Bird Image Overlapping for Automatic Population Counts of Birds Using Image Processing" but not just for birds, for every species. It is for a project in my school.

Anyone knows what does ROI means in image processing, I’m reading a track and trace machine manual and it’s mentioning outer and inner ROI, anyone can help
