Peak detection in a Filled area 2-D plot

Hello,

i've been working on "Filled area 2-D plot",

I have this image(that i attached) ....how can i detect maximum value of Y?

as you see in this image Y is 11.

Thanks a lot.

Can you attach the data?

hello

i have an image from a face, i ploted this image using (Filled area 2-D plot),

i attached my result, i wanna find maximum Y from plot(as you see in this image is Y=11)

I coudnt use ''findpeaks'' because my output type from this kind of plot(Area) is 1*92 Area

Give us data and code to reproduce that plot.

You can use findpeaks, available in Signal Processing Toolbox to find local maxima.

Thank you

how can i use this command for (area)?

[Sumeet Singh]

If data is available to you then you may try this code.

[max_col, rows] = max(data)
[peak, col_idx] = max(max_col) %peak -> peak value in data, col_idx -> column index of peak value
row_idx = rows(col_idx) %col_idx -> row index of peak value

Stacked value can be calculated by summing up the row containing peak value
