CEC is a C++ library typically used in Internet of Things (IoT), Arduino applications. CEC has no bugs, it has no vulnerabilities, it has a Strong Copyleft License and it has low support. You can download it from GitHub.

Arduino library for HDMI CEC communication. Original code at: (c) Phil Burr and Andrew N. Carr. This is an Arduino library which implements the HDMI v1.3a CEC wire protocol which allows communication with HDMI CEC capable devices. A typical usage scenario would be a Home Theater PC environment which uses HDMI but does not support CEC. This would allow the HTPC to communicate with other HDMI CEC equipment. Note: the nice thing about CEC is that it's a bus. Consequently, the Arduino can be connected to a different HDMI port (= "physical address") than the one it should control. Therefore, the address given in the example code is the address of the port where the CEC-less source device is plugged in. I have tested the example with a somewhat dated Philips TV (40PFL5605K), and can now use my remote control for Kodi etc. Other TVs may have different quirks - if it doesn't work, connect something that does work (e.g. a FireTV), enable promiscuous mode and observe the traffic on the serial console. Unknown messages can be directly pasted into CEC-O-MATIC (to decode them without having to dig through the spec. Note: most HDMI sinks also want +5V supplied on pin 18 before they start using the port. The bold numbers in the schematic below correspond to the HDMI pin numbers where the signals should be connected (see also

            Need assistance with the simple task. I’m playing around with the LISC dataset that contains hematological images taken from peripheral blood and segmentation masks of manual ground truth for these graphical samples. The task is the following:

            1. Segment isolated leukocytes by removing/cropping irrelevant background elements using the segmentation masks given in the dataset. Try this on one sample only.
            2. Once accomplished, go through the whole folder, and segment/crop the rest of the samples.

            Results should be like this (these were obtained via a combination of Mask R-CNN, GrabCut, and OpenCV — but not suitable for the current project I’m working on):

            The change in colors is the result of the specified heatmap (viridis instead of binary) as noted above in comments.

            The output image has different coloration than the input image because OpenCV uses BGR rather than RGB for colors, so it's likely your red and blue channels are swapped. If you read an image with OpenCV and plot with Matplotlib or vice versa. There are two easy solutions:

            1.) Both read and plot images with OpenCV. You can replace plt.imshow(im_orig) with:

            It's not you doing something wrong, it's also not the SDK, it's the service. The service seems to substantially deviate from the OData V2 conventions as well as basic HTTP conventions.

            You can work around this by leveraging the low-level APIs of the SDK even more. Create the update request fully manually with the payload the service requires, e.g.:

            To update an entity you should get it from the service first. That is regardless whether you are using:

            1. PATCH which will update only changed fields
            2. or PUT which will send the full entity object

            Currently you are creating a new entity object via the builder: ContactOriginData.builder(). Instead, please use the corresponding getContactOriginDataByKey() method of your service to first retrieve the entity to update from the service. Actually many services will force you to do this to ensure you are always editing the latest version of your data. This often happens via ETags which the SDK will also handle for you automatically.

            You can find more information about the update strategies from the SDK on the documentaiton.

            Edit: As you pointed out in the comments the actual goal is to create an entity and the specific service in question only allows PUT and PATCH to create objects.

            In that case using replacingEntity() (which translates to PUT) should already work with your code. You can make PATCH work as well by replacing the builder approach with a constructor call + setter approach.

            Answered 2021-Feb-15 at 21:09

            it seems likely you're not only re-initializing tf for each frame, but you're starting a new process for each frame, then killing it after it's done. One of the benefits of a Pool is letting some initialization happen in the child process, then keeping it around to execute multiple tasks. I think a simple solution would probably be re-arranging your code to look something like this, though it's hard to know with what you've posted.

            Using graph6 format with graph-tool

There must be an easy way to do this... any help would be appreciated.

            The graph6 format looks annoying to work with, but fortunately the documentation mentions a tool named showg for pretty-printing graphs. It's easy to simply parse the output of that program.

            First, build the showg tool. (Use clang or gcc as appropriate for your system. Or just download the binary they provide on their website.)
