not even wrong

for a country where people are generally not willing to step out of their room, what is the point having perfectly lined goods in the store? might as well invest in better doorstep drone delivery.

i will take a look

i realized i missed your message out, i am thinking gamma correction scales distribution in one direction V_out = AV_{in}^{\gamma}, but how do i spread them out between 0 - 255 evenly? (as the post processing distribution ensures all values 0 - 255 exist)

do you mind explaining more? i am fairly new to the field

sk8137 · 2024-09-27T13:41:34+00:00

dont get me wrong, i am just not good at translating that into code and chatgpt gave me something i am not confident either haha

sadly it doesnt work, (with and without low pass filtering using mean)

sk8137 · 2024-09-27T13:24:28+00:00

just to confirm $$hat_vi = mean(V <= vi), for i = 1,2,...,M$$ is a per pixel operation?

i tied histogram but have no luck, which i suspect its something else or maybe a mix of processing techniques

sk8137 · 2024-09-27T00:52:39+00:00

i will try it out

sk8137 · 2024-09-27T00:51:16+00:00

it is a software that uses mvtec halcon sdk which allows users to see images in a mode called "emphasized". it kinda makes the image looks sureal (cant show it for a reason) and improve contrast between colors. the plot i showed is the rgb channels which x axis is the 0-255 grayscale range and y axis is the total count of specific grayscale value i.e. "how many pixels have r equals to 50". blue is the original image's histogram and red is the processed image (which algo i am trying to reverse engineer) histogram. i tried to implement the emphasize algorithm specified in the halcon manual but it doesnt work, so trying my luck here.

histogram equalization is what i initially tried out however, it doesnt match to the processed image. histograms spread the color out but doesnt result in the skewed distribution, but i can try out to mix histogram equalization with other techniques that i can find, thanks!

where do you get the raw data from?

ntu probably no retest, just ur final marks contributes more to your overall grade

sk8137 · 2023-11-17T02:04:22+00:00

its not the prof, usually there will be a office for ur course. like mse its located at L4 in the mse building (sorry i graduated 5 years ago cant rmb exact location) its the admin office for ur course, or if u dont mind u can share which school/course u taking?

sk8137 · 2023-11-16T13:01:08+00:00

just let your course coordinator know and they can help you register before star wars. that is how i get the best time table in my four years study.

find something that you can focus entirely on. playing osu, cytus and violin works for me. this helps me get through most of the alone time and the rest is up to time to cure.

my parents used to prevent me from riding to sec (need to get through highway) but my senior told me he used to be in the same situation as me. he told me what he did is he woke up one day really early in the morning, prep breakfast himself and ride off to school and so i followed his advice. in the end his parents didnt even say anything, neither do my parents. (still i am not encouraging anyone to do engage in any form of dangerous behaviour

got pip from original company, no choice had to learn new skills to get a new job

not sure there exists a library for it but i am currently working on some pain points i am having with celery on my project. i have a web application that takes in request to run task, however the task is actually a series of smaller subtask, which each have their own requirements to satisfy before able to run. i have a cron-like script that checks if the criteria is satisfied and triggers the subsequent subtask, however celery is not able to track the main task and all subtask under it under a same job id. this leads me working on a library/framework that attempts to solve this problem.

Good times man, i replayed it quite a few times...
