What is the best deep learning algorithm to convert Image data to numeric data? As my project required numeric data from image data for adjusting the value for voltage stability. Kindly need assist as im new to this

Image data is numeric data.
There are, however, times when you want to change the numeric representation, such as by using im2double()
Are you possibly asking about having it interpret a graph? If so then see the File Exchange for the tag "digitize" -- I tagged a number of programs last year.
Possibly OCR (Optical Character Recognition) could also be important for interpreting graphs. That has more often been done with shallow networks instead of deep networks, but deep networks could also be used, especially for hand-written material. Deep networks could also be important for interpreting blueprints and mechanical drawings.

I mean how to get the values data from an image data so that the values data can be alter for further step of the programming?

Please show a sample image and describe the data that you want to extract from it.
Sorry, I want to do Convolutional Neural Network for regression. But the problem is, I have the data in matrix (57x9) where it has input and target data(last column). Should I convert these data matrix back to image so that it can be train by CNN input layer? Or is there any other way I can solve it ?
You could use
data8 = im2uint8(rescale(data));
and then you could imwrite() that.
However if you are doing a bunch of those, it would be better if you held off doing the rescaling until after you knew the minimum and maximum over all of the data, so that the interpretation from image to image could be consistent.
CNN mostly does not care whether the data comes from a datastore object or imageDatastore, but there are some cases where you need an augmentedImageDatastore to bind the class information in smoothly... I think. Not sure; there might be ways around that.

Can I convert a group of image data into numerical data???

How is the group of image data currently stored?
