How can I change the product image size in the new Luna theme from square to rectangle 223 px x 330 px - it was possible in the old version - but can't find where to change it in the new one.

I am making a card recognition project on MATLAB and I am stuck at this point. There are images of cards and on an image I want to define the smallest rectangle that takes the card inside. Example like below
Original image
Converted image
I am currently able to convert the image to black and white (leaves me only the cards white spaces), I want to define the rectangles by the whole white spaces. E.g., if I have 3 non-lapping cards in my image, I want to have 3 images like above (doesn't matter if another cards edge appears on the image, the important part is that rectangle must pass through the edges of the selected card).
I have tried edge definition methods but wasn't successful. Thanks for your help already.
I recommend you use regionprops function from the image processing tool box, i.e.,
bb = regionprops(yourImage, 'boundingbox');
which will return the bounding box. There is a nice MATWORKS video here and you can jump to about minute 26 for what you need.
How can I increase the point size in Meshlab for point clouds? I found how I can show / hide specific PCs, but I do not see where to change their display properties : size, color, symbol ...
If you are using Meshlab 1.3, you have to do 3 steps:
View->Show Layers Dialog to enable the panel at the right.
Render->Show Vertex Dots, to show the vertices as small circles.
There is a Dot size field in the Layer Dialog that let you change the size of the circles.
If you are using Meshlab-2016 or later, it is even easier...
Click on the tab of vertex and choose the option Dot Decorator (1)
Change the size of dots with the Point Size Bar (2)
In MeshLab, you can just use Alt + mouse wheel to control point size.
Or you can find the point size setting in:
Tools->Options->MeshLab::Appearance::pointSize.
I'm trying to manually create label files for some images in YOLO/Darknet, and I need to fill in some values for the bounding boxes.
From the YOLO website (https://pjreddie.com/darknet/yolo/):
Now we need to generate the label files that Darknet uses. Darknet wants a .txt file for each image with a line for each ground truth object in the image that looks like:
[object-class] [x] [y] [width] [height]
Where x, y, width, and height are relative to the image's width and height.
The class, width and height are straight forward, but I'm wondering how to represent the center coordinates for the box, [x] and [y] , as I don't know where the (0,0) reference is allocated.
Thanks
For others who might be wondering, I found the answer to be at the top left corner of the image.
I'm trying to create MATLAB figures to put into a paper. The paper has very specific sizing instructions for figures that I'm having trouble matching in MATLAB. The figures need to be no greater than 3.5" width, >300 DPI, with 8pt font.
In my code, I use the following to try to set the parameters:
set(gcf,'PaperUnits','inches');
set(gcf,'PaperPosition',[0 0 3.5 3.5]);
xlabel('x-axis label','FontSize',8);ylabel('y-axis label','FontSize',8);
set(gca,'FontSize',8);
print('-djpeg','-r300','filename.jpg')
This should be giving me a 300 DPI, 3.5"x3.5" JPEG image with an 8pt font size. However, when I import the image into Word, it becomes 6.5" x 6.5" and the font size is larger than Word's 8pt font. Even if I resize the image, the font size is still too large, though it should maintain the same DPI. Are the FontSize and PaperPosition parameters not working as I expect they should or is Word doing something strange for importing?
The font size issue was caused due to differing fonts used in MATLAB and Word. Once I learned about set(gca,'FontName'), the font size seemed to be correct when the image was manually resized to 3.5" x 3.5".
The image size issue seemed to be related to saving it as a JPEG. Once I swapped to PNG, the image was the correct size by default. Looking into the JPEG properties, it had the correct number of pixels for a DPI of 300 at 3.5", the sole issue was that it would have to be manually resized. Thanks for the comments that led me to finding a solution.
I created a 8.5x11.0 inches image # a 300dpi setting in photoshop.
When i go to use this as a background image in report designer the image looks hugeee.
It's not fitting within the 8.5x11.0 page.
Is there a way to resize this image correctly so that it will fit correctly within a 8.5x11.0 letter size page?
Thanks in advance,
with the information you gave, i believe your problem is problably in the group Size/dpi
You saved an image of size 8,5 x 11 inches # 300 Dpi (dots per inch) that calculates to aproximately an image of 2550 x 3300 pixels.
Now if your "report designer" software looks only at the size in pixels and assumes a dpi value diferent then the one you used, say for example 72 dpi, your 2550 x 3300 pixels image would actually be something like 45,8 x 35.4 inches.
So, my advice is, find out what are the characteristics your solftware is especting, aparently it is not 300dpi.
If you can´t find the information, try commonly used dpis like 72dpi or 150dpi.
