Edge Detection Along Blood Vessel in Matlab -


i trying specify line across blood vessel in image, , have matlab specify edges of vessel (which contained within line). next part comparing changes in distance between these edges on time (so across 1000x more images).

i have tried following code started:

i = imread('obj1.tif'); imshow(i,[]); improfile

and looking @ available methods detect edges intensity along line gets plotted (tangents, maxima/minima etc) not convinced best method. looked other tools on matlab such canny method, sobel etc, examples of these show how detect edges throughout entire image. coding skills not sufficient have algorithms specified along single line of users choosing. methods have looked @ on pubmed seem more complicated perhaps need.

does have ideas or suggestions point at?

thank you

c# - Send Image in Json : 400 Bad request -

from android trying send image class of data, iis webservice. (c#) the problem 400 bad request . the image being encoded base64 . , placed json rest of class elements. my guess base64 not valid inside json. server not understand it. if set string "" , post accepted fine. so question is, how make base64 valid within json array? ( tried url.encode no success). or how should send image android webservice? gson gson = new gson(); string json = gson.tojson(record); // record has param { string base64photo } how big image? i'm pretty sure surpassing iis json size limit (default 4 mb). check http://geekswithblogs.net/frankw/archive/2008/08/05/how-to-configure-maxjsonlength-in-asp.net-ajax-applications.aspx or http://www.webtrenches.com/post.cfm/iis7-file-upload-size-limits good luck!
