            How to get the SSIM comparison score between two images?
            Asked 2022-Mar-24 at 01:16

            I am trying to calculate the SSIM between corresponding images. For example, an image called 106.tif in the ground truth directory corresponds to a 'fake' generated image 106.jpg in the fake directory.

            The ground truth directory absolute pathway is /home/pr/pm/zh_pix2pix/datasets/mousebrain/test/B The fake directory absolute pathway is /home/pr/pm/zh_pix2pix/output/fake_B

            The images inside correspond to each other, like this: see image

            There are thousands of these images I want to compare on a one-to-one basis. I do not want to compare SSIM of one image to many others. Both the corresponding ground truth and fake images have the same file name, but different extension (i.e. 106.tif and 106.jpg) and I only want to compare them to each other.

            I am struggling to edit available scripts for SSIM comparison in this way. I want to use this one: https://github.com/mostafaGwely/Structural-Similarity-Index-SSIM-/blob/master/ssim.py but other suggestions are welcome. The code is also shown below:

            Can Python be invoked against a script file with a parameter-name for the script filepath?
            Asked 2022-Feb-21 at 20:40

            Does anyone know if the python3 command on Linux can have some sort of SOME_NAMED_OPTION=filename.py after it rather than just calling python3 filename.py?

            I have a job scheduling tool I'd like to execute a Python script with that's kind of dumb.

            It can only run Linux CLI commands commandname param1 param2 param3 or as commandname AAA=param1 BBB=param2 CCC=param3.

            There's an existing business convention of putting filename.py as param #1 and then just making sure your script has a lot of comments about what the subsequent numerically ordered sys.argv list members mean, and you set the scheduling tool into its first mode, so it runs python3 filename.py world mundo monde, but it'd be awesome to be able to name the scheduling tool's parameters #2+ so I can write more human-friendly Python programs.

            With python3 -h I'm not finding a way to give a parameter-name to filename.py, but I thought I'd see if anyone else had done it and I'm just missing it.

            It'd be cool if I could have my scheduling tool run the a command more like python3 --scriptsource=filename.py --salut=monde --hola=mundo --hello=world and then write filename.py to use argparse to grab hola's, hello's, and salut's values by name instead of by position.

            Yes, a try/except is the best way to go about this.

            Per the docs, pickle is capable of recursively pickling objects, that is to say, if you have a list of objects that are pickleable, it will pickle all objects inside of that list if you attempt to pickle that list. This means that you cannot feasibly test to see if an object is pickleable without pickling it. Because of that, your structure of:

            A "multiarch" Python interpreter built on MacOS is intended to target MacOS-on-Intel and MacOS-on-Apple's-arm64.

            There is absolutely no binary compatibility with Linux-on-Apple's-arm64, or with Linux-on-aarch64. You can't run MacOS executables on Linux, no matter if the architecture matches or not.

            Custom conflict handling for ArgumentParser
            Asked 2021-Dec-22 at 21:48
            What I need

            I need an ArgumentParser, with a conflict handling scheme, that resolves some registered set of duplicate arguments, but raises on all other arguments.

            What I tried

            My initial approach (see also the code example at the bottom) was to subclass ArgumentParser, add a _handle_conflict_custom method, and then instantiate the subclass with ArgumentParser(conflict_handler='custom'), thinking that the _get_handler method would pick it up.

            The Problem

            This raises an error, because the ArgumentParser inherits from _ActionsContainer, which provides the _get_handler and the _handle_conflict_{strategy} methods, and then internally instantiates an _ArgumentGroup (that also inherits from _ActionsContainer), which in turn doesn't know about the newly defined method on ArgumentParser and thus fails to get the custom handler.

            Overriding the _get_handler method is not feasible for the same reasons.

            I have created a (rudimentary) class diagram illustrating the relationships, and therefore hopefully the problem in subclassing ArgumentParser to achieve what I want.

            Motivation

            I (think, that I) need this, because I have two scripts, that handle distinct parts of a workflow, and I would like to be able to use those separately as scripts, but also have one script, that imports the methods of both of these scripts, and does everything in one go.

            This script should support all the options of the two individual scripts, but I don't want to duplicate the (extensive) argument definitions, so that I would have to make changes in multiple places.
            This is easily solved by importing the ArgumentParsers of the (part) scripts and using them as parents, like so combined_parser = ArgumentParser(parents=[arg_parser1, arg_parser2]).

            In the scripts I have duplicate options, e.g. for the work directory, so I need to resolve those conflicts.
            This could also be done, with conflict_handler='resolve'.

            But because there are a lot of possible arguments (which is not up to our team, because we have to maintain compatibility), I also want the script to raise an error if something gets defined that causes a conflict, but hasn't been explicitly allowed to do so, instead of quietly overriding the other flag, potentially causing unwanted behavior.

            Other suggestions to achieve these goals (keeping both scripts separate, enabling use of one script that wraps both, avoiding code duplication and raising on unexpected duplicates) are welcome.

            Example Code ...

            Answered 2021-Dec-22 at 01:02

            For a various reasons -- notably the needs of testing -- I have adopted the habit of always defining argparse configuration in the form of a data structure, typically a sequence of dicts. The actual creation of the ArgumentParser is done in a reusable function that simply builds the parser from the dicts. This approach has many benefits, especially for more complex projects.

            If each of your scripts were to shift to that model, I would think that you might be able to detect any configuration conflicts in that function and raise accordingly, thus avoiding the need to inherit from ArgumentParser and mess around with understanding its internals.

            I'm not certain I understand your conflict-handling needs very well, so the demo below simply hunts for duplicate options and raises if it sees one, but I think you should be able to understand the approach and assess whether it might work for your case. The basic idea is to solve your problem in the realm of ordinary data structures rather than in the byzantine world of argparse.

            I am trying to digitize the kid's drawing into SVG or transparent png file format so that they can be used in Scratch. The white paper should be replaced by transparent background and all the drawing part should be preserved.

            My plan is to get the outest contour of the drawing and generate a mask, then use the mask to get the drawing part without paper background.

            The problem is the drawing may not consecutive which means there may have some small holes leading to break the entire drawing contour to many many small contours.

            Now I want to concatenate the near outest contours to form a big outest contour for masking.
