android - Displaying a route on a floor plan image -


i have floor plan on walls black, doors orange , target red. want make app given specific point on image, route target calculated , displayed. have routing method, in matlab , each position , object defined in code , doesn't use image. know how scan image identify walls, doors , target color in order apply routing method , display route on image of map (i guess should use drawable that).

this steps implement pathfinding algorithmm image.

  • upload image
  • apply color detection hsv(in real life easy control light changes format) algorithm obtain objects separately.
  • make new binary matrix 1 floor , 0 obstacles.
  • apply binary matrix occupancy grid algorithm(this reduce matrix because in pathfinding algorithm need processing).
  • i recommend use diijistrak or star algorithm, in 2 cases need construct adjacency matrix.

the graph theory understand better.good luck!!

you can work in processing ide rapid prototipyng , migrate processing ide core eclipse, need implement papplet class in eclipse project, , can compile app android.

How to group boxplot outliers in gnuplot -

i have large set of data points. try plot them boxplot, of outliers exact same value , represented on line beside each other. found how set horizontal distance between outliers in gnuplot boxplot , doesn't much, apparently not possible. is possible group outliers together, print 1 point , print number in brackets beside indicate how many points there are? think make more readable in graph. for information, have 3 boxplots 1 x value , times 6 in 1 graph. using gnuplot 5 , played around pointsize, doesn't reduce distance anymore. hope can help! edit: set terminal pdf set output 'dat.pdf' file0 = 'dat1.dat' file1 = 'dat2.dat' file2 = 'dat3.dat' set pointsize 0.2 set notitle set xlabel 'x' set ylabel 'y' header = system('head -1 '.file0); n = words(header) set xtics ('' 1) set [i=1:n] xtics add (word(header, i) i) set style data boxplot plot file0 using (1-0.25):1:(0.2) boxplot lw 2 lc rgb '#8b0000...

bash - Performing variable substitution in a string -

i have string contains use of variable, , i'd substitute variable's value string. right best have is #!/bin/bash foo='$name; echo bar' name="the name" expanded="$(eval echo "$foo")" echo "$expanded" which has obvious defects: prints the name bar while i'd print the name; echo bar instead of eval can bash's regex matching bash's string replacement: foo='$name; echo bar' name="the name" [[ "$foo" =~ \$([[:alnum:]]+) ]] && s="${!bash_rematch[1]}" && expanded="${foo/\$${bash_rematch[1]}/$s}" echo "$expanded" name; echo bar
