# How do you write an undefined slope in standard form

For other uses, see Standard deviation disambiguation. Octagon The 'Octagon' kernel is a 8 sided shaped kernel. And was specifically designed to match the ' Octagonal Distance Metric '.

Do not confuse the two as they are very different kernels. Here are the resulting kernels for small radii Note that at radius 1, you get the same kernel as a "Diamond" kernel.

Because of this the default octagon size is of radius '2'. From this point on I will be using a special kernel2image script to generate images of the kernels as they are much clearer than using a raw "dilate-scale" method as above.

Remember however the kernels are in generally very small, though Octagon and Disk kernels see next can become very large for specific uses. The "Octagon" kernel was added in IM v6. Disk The 'Disk' kernel is as you would expect, a circular shape. And is commonly used when a very large morphological kernel is needed.

Note however it is a aliased boolean circle. However the radius argument for a disk can be a floating point number, which allows you to produce a quite a range of shapes, using small radii. Disks of this size or larger are especially good for generally rounding and smoothing image shapes.

The final size of the kernel containing the disk is the 'radius' value rounded down, times 2 plus 1. As such the default 'Disk: Note that a value less than one but not zero will always produce a single pixel kernel, though that is not very useful.

After that the kernel tends to mostly produce kernels that can also be generated using the previous kernel types. It is only as the radius gets large that true disk-shaped kernels start to emerge.

The most important thing to note is that a disk with a fractional radius works a lot better than using a integer radius.

Whenever the slope (m) is undefined it means that when you try to calculate the slope given any 2 points on the line you'll end up with a zero in the denominator, which is undefined. That is, with an undefined slope you end up with a vertical line, which has the equation "x=some number"/5. A lot of people like using the formula, which is the x 1, y 1, x 2, y 2 formula. If you do it this way, you'll get the exact same answer. You plug in numbers y 2 minus y 1 over x 2 minus x 1 (y 2. There are three output files specified, and for the first two, no -map options are set, so ffmpeg will select streams for these two files automatically.. vetconnexx.com is a Matroska container file and accepts video, audio and subtitle streams, so ffmpeg will try to select one of each type. For video, it will select stream 0 from vetconnexx.com4, which has the highest resolution among all the input video streams.

Adding a fraction of about 0. Plus The 'Plus' kernel is actually a little different to the other morphological shape kernels, in that it is designed to represent a specific 'shape' rather than a simple 'neighbourhood' around a pixel. Using a larger 'radius' with this kernel does not simply increase the size of the kernel, but lengthens the arms of the resulting plus sign.

The thickness of the arms however does not increase. The default size of a 'Plus' kernel is a radius of 2, producing 2 pixel 'arms' around the central 'origin'.

Note that a 'Plus' kernel is a generally not used for normal morphological methods, and should be avoided for such purposes. However it is a very useful if you are wanting to find and highlight single points in an image, such as I do later to display Skeleton Information.And here’s the graph.

Note again that we just ignore the negative values and fractional values (non-integers) of \(x\) at this time: Now, look at the slope (or how much the line is slanted up, in this case).

## Morphology Introduction

Since the slope of a vertical line is undefined you can't write the equation of a vertical line using neither the slope-intersect form or the point-slope form.

But you can express it using the standard form. An equation that has an undefined slope is a vertical line. A vertical line is represented by x = a number.

## Perpendicular Lines

You cannot write an equation for a vertical line in slope intercept form (because of the undefined slope) but u can write it in standard form. Answer: x=2 Find standard form of equation with undefined slope and point (2,5) Undefined slope is a vertical line of x=a for some constant a Therefore, the equation of the vertical line that passes through (2,5) is x=2 since the x-coordinate is constant independent of the y variable.
