1. Apparatus for supporting an object on a vertical wall, said apparatus comprising a mounting rail; means for mounting said rail on said wall; a bracket; and means for mounting said bracket on said object, said rail having a body portion terminating in a first flange offset to one side from said body portion, said bracket having a body portion terminating in a reversely turned lip, said lip embracing said flange, and said body portion of said flange bearing upon said flange.
2. The apparatus according to claim 1 wherein the means for mounting said rail on said wall comprises a first screw having a head and the means for mounting said bracket on said object comprises a second screw having a head, the head of said first screw confronting the body portion of said bracket and the head of said second screw confronting said rail, the first and second heads being so positioned that said bracket is movable along a path parallel to said rail with no interference between the heads of said screws.
3. The apparatus according to claim 1 wherein said rail has a second flange offset to one side of said rail body portion and parallel to said first flange, said body portion of said bracket being of such length as to bear upon said second flange.
4. The apparatus according to claim 1 wherein said lip has a thickness corresponding substantially to that of said rail body portion.
5. The apparatus according to claim 1 wherein said lip is spaced from said bracket body portion a distance corresponding substantially to the thickness of said first flange.
6. The apparatus according to claim 1 wherein said object has a recess therein and wherein said bracket is accommodated in said recess.
7. The apparatus according to claim 6 wherein said bracket and said recess have corresponding dimensions.
8. The apparatus according to claim 1 wherein no part of said bracket projects beyond a side edge of said object.
9. In combination, an object, a vertical wall; and means mounting said object on said wall, said means comprising an elongate rail secured to said wall in a horizontal position, said rail having a planar body portion flush against said wall, a first flange spaced from said wall and extending upwardly from said rail body portion to form an upwardly open groove at a level above that of said rail body portion, a bracket secured to said object and confronting said rail, said bracket having a planar body portion terminating at the upper end thereof in a reversely turned, downwardly extending lip forming a space between said lip and said bracket body portion, said lip being accommodated in said groove and said flange being accommodated in said space, said groove and said lip having substantially corresponding thicknesses thereby enabling said bracket body portion to confront and bear upon said first flange.
10. The combination according to claim 9 wherein said bracket has a second flange extending downwardly from said rail body portion and being coplanar with said first flange, said bracket body portions spanning said first and second flanges and bearing upon both of said flanges.
11. The combination according to claim 9 wherein said rail and said bracket are secured to said wall and said object respectively by screws having heads which project beyond the respective rail and object a combined distance enabling said object to be slid longitudinally of said rail without interference between said heads.
12. The combination according to claim 9 wherein said object has a recess therein, said bracket being accommodated in said recess.
13. The combination according to claim 12 wherein no part of said bracket projects beyond a side edge of said object.
14. The combination according to claim 12 wherein said recess and said bracket have substantially corresponding depth dimensions.
15. The combination according to claim 9 wherein said rail body portion has a longitudinally extending groove therein defining an area of reduced thickness of said rail body portion.
The claims below are in addition to those above.
All refrences to claim(s) which appear below refer to the numbering after this setence.
1. A method of recognizing an object in a digital image, the method comprising:
generating fractal map of the image including estimating a fractal dimension for at least one pixel of the image, the fractal dimension of the pixel given by
d
p

log
\u2061
(
N

)
log
\u2061
(
L

)
where dp is the fractal dimension of the at least one pixel of the image, N2 is the sum of the pixel values in an L2\xd7L2 structuring element, N1 is the sum of the pixel values in an L1\xd7L1 structuring element, and L2 and L1 are the sizes (in pixels) of the respective structuring elements;
isolating the object by segmenting the fractal map;
locating the object on the fractal map; and
confirming the object based on pixel value of a pixel at a corresponding location in the digital image.
2. The method of claim 1 wherein locating further includes shrinking the object to a pixel, the pixel characterized by a coordinate pair, (x,y), representing a location in the fractal map.
3. The method of claim 1 wherein confirming further includes:
estimating a background level of the image;
generating a background adjusted image by subtracting the estimated background from the image;
setting a threshold based on the background adjusted image;
determining if a pixel value of a pixel in the background adjusted image is greater than the threshold, the pixel located at the corresponding location of the object in the fractal map; and
recognizing the object if the pixel value is greater than the threshold.
4. The method of claim 3 wherein estimating the background further comprises:
(i) determining a first minimum pixel value from a first set of pixels, the first set of pixels defining a first line spanning the image;
(ii) determining a second minimum pixel value from a second set of pixels, the second set of pixels defining a second line spanning the image; and
(iii) estimating the background by selecting the greater of the first minimum pixel value and the second minimum pixel value.
