Tracking colors

I'm just getting started with Python, and I want to do a bit of color
tracking using VideoCapture. However, I've never worked with video or
images, so I'm a little at a loss. How would I use VideoCapture to
track a specified color, and its coordinates?

There's really no easy way to do this. You'll have to convert the image to
an array of pixels, then search through them to find a block of the color
you're interested in. Remember that camera sensors are real-world devices,
so the actual pixel values vary slightly from frame to frame. You'll have
to look for a range.

I'm using an Access database to drive a web site and the colors of various table backgrounds are stored in Access. I want users of the Access database to be able to select colors for the site, but my mappings between named colors, HEX values and the Long Integer values used in Access are not jibbing. Anyone have a nice list laying around? Danny J Lesandrini dlesandrini@hotmail.com

Mike, I have databse that creates a "tracking number" based on the selections made on the form via concatenating. At the end of the tracking number, I need a two digit (01-99) sequence number by product group for each customer. Hpw do I do this without creating a table for each customer and each product group with autonumbers.

Hey all, This is a general question. Here's my scenario: We have a legacy database. The core table within contains almost 4 million records in SQL Server. Currently we have a web front end which allows uses to search through the database for the information they need. What the client wants is a web front end which allows some users to edit the core table above. No problem. What the client also wants is for the non-editable web front end...

So I figured out that if you use this html: http://wwwapps.ups.com/WebTracking/processInputRequest?sort_by=status&tracknums_displayed=1&TypeOfInquiryNumber=T&loc=en_US&InquiryNumber1=<TRACKING NUMBER HERE>&track.x=0&track.y=0 it will link you directly to the UPS tracking page for the specified tracking number. I think it would be really cool to be able to click a tracking number record in a table and have it take you directly to the...

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,...
