Processing 3.x not recognizing random() function


Processing 3.x not recognizing random() function

help you fix your problem You're calling the random() function from your Tree class, not your sketch class. That won't work, because only the sketch class knows about the random() function.
One approach to fix this is to pass an instance of your sketch into the Tree class, then use that to get to the random function. Something like this:
code :
void setup(){
   Tree tree = new Tree(this);
}

class Tree{

   public Tree(PApplet sketch){
      float x = sketch.random(100);
   }
}

Hope that helps To start with, this problem reminded me a bit of these demo's that might be useful to learn from:
The DNA microarray image processing The Matlab Sudoku solver The Iphone Sudoku solver blog post, explaining the image processing
code :
f_makebw = @(I) im2bw(I.data, double(median(I.data(:)))/1.3);
bw = ~blockproc(im, [128 128], f_makebw);
bw = bwareaopen(bw, 30);
se = strel('disk', 5);
bw = imerode(bw, se);

% Detect the squares and cricles via morphology
[B, L] = bwboundaries(bw, 'noholes');
stats = regionprops(L, 'Extent'); 
extent = [stats.Extent];
idx1 = find(extent > 0.8);
bw = ismember(L, idx1);
Tesseract not recognizing anything after image processing

seems to work fine I've tested a little with your images. I think the main problem is the poor image quality. Try images in higher resolution, that could work a lot better. I assume you only want the item names? If yes, then delete the "Buy Now for:" and the coins + the according numbers also (just paint them black like the rest), that made it better for me! Also play around with the different settings of Tesseract I had the best results with psm 1 and 6 I think.
Conclusion: Higher image quality (resolution) should work the best!
Android studio 3.1 not recognizing jar annotation processing

may help you . If you have everything inside the same artifact, — annotation processor, it's annotations and library classes, used by processor users, Android Gradle plugin requires you to declare two dependencies on the same artifact:
code :
annotationProcessor project(':processor')
compile project(':processor')
annotationProcessor files('libs/processor.jar')
compile files('libs/processor.jar')
annotationProcessor project(':processor') // processor-only jar
compile project(':processor-api') // annotations and classes for user code
Is there any random.choices() function in Python Processing

Is there any random.choices() function in Python Processing

I hope this helps . Python mode for Processing is built on Jython, and Jython still hasn't crawled out of the Python 2 era (it only moved to Python 2.7 compatibility, from 2.5, in 2015, half a decade after 2.7 released).
random.choices was introduced in Python 3.6; even if Python mode for Processing offered full access to all Python features (and I have a hard time determining if it does), Jython's 2.7 compatibility means it has almost no features introduced after Python 3.1, so random.choices is not available without reimplementing it from scratch. Of course, the code for random.choices is open source and posted online, so you could always just backport it to Python 2 yourself (along with itertools.accumulate, which it relies on).
Not recognizing png files for image processing

help you fix your problem I'm trying to add png resolution to our image processing code. I'm getting the following error which i do not know how to resolve. , Check what value is being returned to $ext.
Based on your code:
code :
my $file = "image_file.jpg";
my ($ext) = $file =~ /(\.[^.]+)$/;
say $ext;
