kandi X-RAY | image-denoising Summary

image-denoising is a Python library typically used in Institutions, Learning, Education, Artificial Intelligence, Machine Learning, Deep Learning, Pytorch, Tensorflow applications. image-denoising has no bugs, it has no vulnerabilities and it has low support. However image-denoising build file is not available. You can download it from GitHub.

This repository contains the code for our work on densoising high resolution images using deep learning paper. Present state-of-the-art methods like BM3D, KSVD and Non-local means do produce high quality denoised results. But when the size of image becomes very high, for ex. 4000 x 80000 pixels, those high quality results come at a cost of high computational time. This time consuming factor serves as a motivation to come up with a model that can provide comparable results, if not better, in much less time. So, I've used a deep learning approach that automatically tries to learn the function that maps a noisy image to its denoised version. I've used thenao as the deep learning framework, and have worked on the publicly available codes provided by the MILA Lab.

            Unable to import SGD and Adam from 'keras.optimizers'
            Asked 2021-May-19 at 15:09

            Trying to run---
            from keras.optimizers import SGD, Adam,
            I get this error---

            Traceback (most recent call last):
              File "C:\Users\usn\Downloads\CNN-Image-Denoising-master ------after the stopping\CNN-Image-Denoising-master\CNN_Image_Denoising.py", line 15, in
                from keras.optimizers import SGD, Adam
            ImportError: cannot import name 'SGD' from 'keras.optimizers'

            as well as this error, if I remove the SGD from import statement---

            ImportError: cannot import name 'Adam' from 'keras.optimizers'

            I can't find a single solution for this.
            I have Keras and TensorFlow installed. I tried running the program in a virtualenv (no idea how that would help, but a guide similar to what I want mentioned it) but it still doesn't work. If anything, virtualenv makes it worse because it doesn't recognize any of the installed modules. I am using Python 3.9. Running the program in cmd because all the IDEs just create more trouble.

            I am stumped. My knowledge of Python is extremely basic; I just found this thing on GitHub. Any help would be greatly appreciated.

            Have a look at https://github.com/tensorflow/tensorflow/issues/23728:

            from tensorflow.keras.optimizers import RMSprop

            instead of :

            from keras.optimizers import RMSprop

            It worked for me.

            Preferred way to decrease learning rate for Adam optimiser in PyTorch
            Asked 2020-May-29 at 13:52

            I have been seeing code that uses an Adam optimizer . And the way they decrease the learning rate is as follows:

            You need to iterate over param_groups because if you don't specify multiple groups of parameters in the optimiser, you automatically have a single group. That doesn't mean you set the learning rate for each parameter, but rather each parameter group.

            In fact the learning rate schedulers from PyTorch do the same thing. From _LRScheduler (base class of learning rate schedulers):

            Tensorflow: My loss function produces huge number
            Asked 2019-Jul-08 at 01:54

            I'm trying image inpainting using a NN with weights pretrained using denoising autoencoders. All according to https://papers.nips.cc/paper/4686-image-denoising-and-inpainting-with-deep-neural-networks.pdf

            I have made the custom loss function they are using.

            My set is a batch of overlapping patches (196x32x32) of an image. My input are the corrupted batches of the image, and the output should be the cleaned ones.

            Part of my loss function is

            sum_norm2 = tf.reduce_sum(prod,0) - I don't think this is doing what you want it to do.

            Say y and y_ have values for 500 images and you have 10 labels for a 500x10 matrix. When tf.reduce_sum(prod,0) processes that you will have 1 value that is the sum of 500 values each which will be the sum of all values in the 2nd rank.

            I don't think that is what you want, the sum of the error across each label. Probably what you want is the average, at least in my experience that is what works wonders for me. Additionally, I don't want a whole bunch of losses, one for each image, but instead one loss for the batch.

            My preference is to use something like
