Can you edit the example above to include a title in the figure above the individual title figures? This is my alternative not sure whether still of use to anyone to the superimpossed grid. But your sample code contains graphics calls like implay and rectangle. I have a sequence of 45x45 matrices each element in each matrix has R,G,B components that I can scroll through, using implay. This is why your images sometimes come out looking pixelated when you blow them up. The resulting image is an m-by- n grid of pixels where m is the number of rows and n is the number of columns in C. I still think what you are asking does not make sense.
The property of the figure contains the alphamap. Steve replied on : 16 of 152 Barbara—I assume you are plotting the x-y locations of boundary vertices using plot. I'm new to matlab so I wouldn't know how to tweak your commands off hand. It is also incredibly non-realistic when used in images. So I would recommend being explicit about image data types whenever it's possible.
I tried a few other endings but no one was working. You also can set the colorbar location using its Location property. The associated axes does not resize to accommodate the colorbar when the Location property is set to 'manual'. I though could be more easy; seems not. Because I need to save these figures.
This interface maintains global state, and is very useful for quickly and easily experimenting with various plot settings. This table lists the supported modifiers when the TickLabelInterpreter property is set to 'tex', which is the default value. You need to detect the dot spacing and possibly the dot grid rotation. To make sure the grid is visible over all pixel colors, I'll use the trick of superimposing two line objects with contrasting colors and line styles. Hello all, I have a patch in the face vertex format. How can I change the way that the image matrix counts itself so that that the bottom left corner is the 0,0 index of the image and it counts up vertically and to the right? By default, imagesc scales the color limits so that image uses the full range of the colormap, where the smallest value in C maps to the first color in the colormap and the largest value maps to the last color. There's not much going on in the code in this post.
Maxi84 replied on : 69 of 152 Hi Mr. Thank you for the help. Can you tell me how to plot arrows with using only the start and end co-ordinates? By default, the colorbar labels the tick marks with numeric values. Applying canny edge detector requires two thresholds, low threshold and high threshold. Value Resulting Location Resulting Orientation 'north' Top of axes Horizontal 'south' Bottom of axes Horizontal 'east' Right side of axes Vertical 'west' Left side of axes Vertical 'northoutside' Top outside of axes Horizontal 'southoutside' Bottom outside of axes Horizontal 'eastoutside' Right outside of axes default Vertical 'westoutside' Left outside of axes Vertical 'manual' Determined by Position property Vertical To display the colorbar in a location that does not appear in the table, use the Position property to specify a custom location.
The plot function by default autoscales the plot so that it encompasses just the data being plotted. As for me,I would like to have only one X and Y coordinates since I want to get digitized information from boundary objects. Kyaw replied on : 144 of 152 Dear Steve, I think this topics seem like what I would like to do for additional requirement that is to put the plotted data of x and y on the image. Another thing is, can I manipulate the coordinate to do ray-tracing on the same picture. I tried to use the plot and imshow many ways and times but I couldn't manage to solve the issue. Anyway we can just interact with the objects? For example, 'Direction','reverse' reverses the color scale. Best of luck with your project.
Either numrows or numcols can be NaN, in which case imresize computes the number of rows or columns automatically to preserve the image aspect ratio. The range of the data is from: -100 until +100. Please, if anyone knows how to solve this issue let me know. Till replied on : 99 of 152 Hi Steve, thanks for the hint. My problem is that the second plot shows up very small on the upper left-hand corner of the figure. I read this post,and copied the code but it seems not to work correctly: Please see the two images below. The same change in data would change the color from dark blue to almost light blue , or in a different place from yellow to orange to red.
If other objects such as a line occupy the axes and extend beyond the bounds of the image, you can pan or zoom to the bounds of the other objects, but no further. Even if the results of the computation are fine, this might lead to think that there is a problem in them when actually it's because of the way imshow handles images with different data types. Specify clims after name-value pair arguments. What i mean by intersection points, is that points were the onions,tomatoes and green papper cuts the gray grid. How can I keep them and only update the background image? I believe that data loss is very difficult to do away with due to single threaded nature of matlab.
However, I am not quite sure how to write it in Matlab. Check out the File Exchange for code to implement draggable graphics objects. Before the colorbar is added the plots are exactly the same size, which I would prefer, but when I add the colorbar the imagesc plot is resized to be smaller than before. Even, I am optimazing some image processing techniques with Matlab programming but still there the results above shown. Pls advise me and I am looking forward to hearing from you good news. Regards, Tracy Matt Whitaker replied on : 6 of 152 Hi Steve, When I have to superimpose lines on images I usually use the line function directly.
