Hi All, I am trying to use JAI to build a histogram of an image i have. I
have posted the code below, and the error I get at runtime. I have taken the
code from the offical java examples, so I am really puzzled why it doesn't
work
public PlanarImage thresholding (PlanarImage source) {
// set up the histogram
int bins = { 256 };
double low = { 0.0D };

Ok I thought I would try to take the program one thing at a time. (If
you remember my last post I am trying to make a histogram with data on
the size of each word)
Anways first .. I obviously need to determine what a word actually is.
I wrote this program on my own without looking at the book or any
other resource once.

Hi, I wrote a C++ class that implements an n dimensional histogram in
C++, using stl maps and vectors. I want to code this up now in Python
and would like some input from this group.
The C++ class was VERY simple..
std::map<std::vector<unsigned short>, unsigned long> histo;
Say for example I want a 3D histogram then std::vector<unsigned short>
would contains

I'm playing around with matplotlib for the first time. I'm trying to
make a very simple histogram of values 1-6 and how many times they
occur in a sequence. However, after about an hour of searching I cannot
make the histogram stay within the bounds of the grid lines.
Here is my example:
pylab.grid()
x_values=
pylab.hist(x_values,6)

How does one do a histogram on only a part of an image?
This is what I found in the PIL documentation about histogram( ):
"""
im.histogram(mask) =list
Returns a histogram for those parts of the image where the mask image
is non-zero. The mask image must have the same size as the image, and
be either a bi-level image (mode "1") or a greyscale image ("L").

this is a programme that counts the "lengths" of each word and then
prints that many of stars(*) on the output . it is a modified form of
K&R2 exercise 1-13. the programme runs without any compile-error BUT
it has a semantic BUG:
what i WANT:
I want it to produce a "horizontal histogram" which tells how many
characters were in the 1st word, how many characters were in the
second word by writing equal number of stars, *, at the...

i was able to create a solution for a Horizontal-Histogram. i was
completely unable to understand this Vertical-Histogram phenomenon.
even though i have looked at the solution at this page:

still i am not able to make sense of many-many things like (on the

Hello everyone,
I am trying to make a histogram for a project in my class and I really need some help. Here is the question that my instructor provided:
Create 1000 Random numbers between 0-100. Create a histogram of the values as a list. Make the bin range 10. Your book goes through a more complicated, but similar exercises.
Here is the code that I have so far:

the 'bins' argument to pylab.hist() is supposed to be an integer or a
list of the bins' lower edges. The default value is 10, more than
that gives smaller bins, as one would expect. Take a look at the
pylab.hist documentation (you can do 'print pylab.hist.__doc__' from
the command interpreter).
You should have no problem plotting a hist of floats. Try...

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,...

Dear forum friends,
With the development of smart home technology, a variety of wireless communication protocols have appeared on the market, such as Zigbee, Z-Wave, Wi-Fi, Bluetooth, etc. Each protocol has its own unique characteristics and advantages, but as a user who is planning to build a smart home system, I am a bit confused by the choice of these technologies.

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. The idea...
