Image Processing on mouth ROI

20 New Member
The attachment "m-004-1.zip" contains "ipskin.pgm " and "m-004-1.pgm".
"m-004-1.pgm" is the mouth region after opening(3x3) and closing(2x2) and labeling.
"ipskin.pgm " is the raw image. Both of the image in binary format.
guys, is it possible to do some image processing techniques and obtain only the mouth region at the middle?
I have tried to get the largest connected component but i got the moustache instead of mouth. What terms can i set so that every image will get the lips only and the rest (moustache and small connected component) become black background?

Thank you.

Best regards,

I read recently that: "if a before-image was made before an interruption in database processing, you use the before-image dump & simply begin processing again from just before the last transaction. Any checkpoints are irrelevant." I'm not a dba here, so bear with me... What I don't understand is, why are checkpoints irrelevant when you did a before image dump? Why not begin from the last checkpoint? Probably part of my problem is...

Hye Friends!!, Happy New Year!! I am Jigar Mehta from India. Currently I am working on a project in which I need to compress some images on the harddisk... I want to make an engine that reads whole BMP image and then compress it.. The target location can be of any type.. BMP, TIFF, JPG or any.. Some data loss will be negligible because all the images are having very high resolution with 32-bit colors (taken from digi-cam).

Hi, we are planning to rewrite an extisting C++ image processing application/library in C#. Now several question arouse where I hope you can help me: So far we allocated a block of memory as image buffer, handed this to a driver dll and got raw image data back in this buffer. We then handed this buffer by reference to another C++ dll to do base image processing on it. Alternativly we copy an area of the whole image to a newly...

Hello all, I am currently implementing a fairly simple algorithm. It scans a grayscale image, and computes a pixel's new value as a function of its original value. Two passes are made, first horizontally and second vertically. The problem I have is that the vertical pass is 3 to 4 times slower than the horizontal, although the code is _exactly_ the same in both cases?! The code itself is very simple. There are 2 loops to scan through...

Hi guys, I used SUSAN corner detector to detect the corners in a mouth ROI. The input image as attached "m-004-1.pgm" and ouput image "004-c.pgm". How can i get rid of other corners and get only the mouth corners? Where should i modify the code? I am using susan corners detector with setting t=10, this is the following link <link removed- weaknessforcats> Thank you. Best Regards, Tommy

Hello, I have a conceptual question. I need to write a program that will take as input a list of images and then process each image individually (extract useful features from the image) Processing each image takes about 20 seconds, and I would like to utilize all available cores / CPUs on a machine to do processing in parallel - for simplicity, I think it'd be easier for now to have each core process an individual image (rather than have...

Overview: Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows. In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...

Let's talk about the concept of autonomous AI software engineers and no-code agents. These AIs are designed to manage the entire lifecycle of a software development project—planning, coding, testing, and deployment—without human intervention. Imagine an AI that can take a project description, break it down, write the code, debug it, and then launch it, all on its own.... Now, this would greatly impact the work of software developers.
